Abstract
Herein, we report a highly efficient Ag(I)-catalyzed indolyzation with Friedel-Crafts alkylation through a cascade cyclization strategy for accessing valuable hybrid heterocycles for the first time. This general strategy consists of forming four C-C/C-N/C-O bonds toward dual annulation reactions of 2-alkynylanilines with methyl benzoate-2-carboxaldehydes and aromatic amines, as well as with salicylaldehydes and malononitrile. Variably substituted new indolo-4H-phthalimidines and indolo-4H-chromenes were synthesized with excellent yields (85-93%) under mild reaction conditions.

Abstract
Indole moiety is often found in different classes of pharmaceutically active molecules
having various biological activities including anticancer, anti-viral, anti-psychotic, antihypertensive,
anti-migraine, anti-arthritis and analgesic activities. Due to enormous applications
of indole derivatives in pharmaceutical chemistry, a number of conventional synthetic
methods as well as green methodology have been developed for their synthesis. Green methodology
has many advantages including high yields, short reaction time, and inexpensive
reagents, highly efficient and environmentally benign over conventional methods. Currently,
the researchers in academia as well as in pharmaceutical industries have been developing
various methods for the chemical synthesis of indole based compounds via green approaches
to overcome the drawbacks of conventional methods. This review reflects the last ten years
developments of the various greener methods for the synthesis of indole derivatives by using microwave, ionic liquids,
water, ultrasound, nanocatalyst, green catalyst, multicomponent reaction and solvent-free reactions etc. (please
see the scheme below). Furthermore, the applications of green chemistry towards developments of indole containing
pharmaceuticals and their biological studies have been represented in this review.

Abstract
Cyclohexan-1,3-dione derivatives are versatile scaffolds for the synthesis of a variety of value-added organic molecules including heterocycles and natural products. Six-membered oxygen heterocycles prepared from cyclohexan-1,3-diones are of much importance as they are intermediate for the synthesis of a number of natural products and several other valuable bioactive molecules which shows anti-viral, anti-bacterial, analgesic, antimalarial, anti-inflammatory, anti-allergic, anti-tumor and anti-cancer activities. These advantages have inspired us to write a detailed survey on the newly developed methods which are very essential in the construction of six-membered oxygen heterocycles. Further, the versatility in the chemistry of cyclohexan-1,3-dione and its derivatives is due to the presence of highly active methylene moiety and its active di-carbonyl groups. Recently, reactions of cyclohexane-1,3-dione and its derivatives with other substrates for instance aldehydes, malononitriles, NMSM, chalcones, isatin etc. have been established for the construction of a variety of six-membered oxygen heterocycles. The studies reported in this review article involved the synthesis of six-membered oxygen-containing heterocycles which includes 4H-chromen-5(6H)-one, 2H-xanthen-1(9H)-one, 2H-xanthen-1,8(5H,9H)-dione, 6H-chromen-2,5-dione derivatives and natural products having six-membered oxygen heterocycles from cyclohexane-1,3-dione and its derivatives as one of the substrate.

Abstract
A family of silica-supported H3PW12O40 (HPW) solid acid catalysts was prepared by wet impregnation of mesoporous SBA-15 and investigated for the solventless synthesis of 3-substituted indoles under mild conditions. Mesoporous SBA-15 facilitated a high dispersion of immobilised H3PW12O40, significantly improving the catalytic efficiency of the heteropolyacid for the desired multi-component transformation. The yield of 3-substituted indoles strongly correlated with HPW loading (which spanned 3.2–51.6 wt %) and corresponding acid strength; the 51.6 wt % HPW/SBA-15 delivered 81% yield of 2-[(1H-indol-3-yl)(phenyl)methyl]malononitrile, approximately five times greater than that of the unsupported HPW, and exhibited a broad substrate scope for aromatic aldehydes.

Abstract
2-Amino-4,5-dihydro-3-furancarbonitriles (ADFCs) have attracted much attention due to
their utility as valuable synthetic intermediates for the preparation of a series of acyclic and cyclic organic
compounds. On the other hand, indoles substituted with furans are highly interesting compounds
displaying a wide range of biological and pharmaceutical activities. However, to the best of our knowledge,
indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles have not been previously reported. A
new and efficient synthesis of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles has been
developed in two steps using water as a solvent. The first step of the sequence involves threecomponent
reaction of phenylglyoxals, indoles and malononitrile under aqueous and catalyst-free conditions
for the synthesis of indole substituted β,β-dicyanoketones. Reduction of the obtained β,β-
dicyanoketones with sodium borohydride in water at room temperature afforded the indole substituted
2-amino-4,5-dihydro-3-furancarbonitriles in good yields. Several substituted phenylglyooxals were reacted
smoothly with indole or 2-methylindole and malononitrile to give the corresponding indole substituted
β,β-dicyanoketones in good yields. Treatment of the obtained β,β-dicyanoketones with sodium
borohydride in water furnished exclusively the indole substituted 2-amino-4,5-dihydro-3-
furancarbonitriles in good yields. We have developed an efficient straightforward access to indole substituted
β,β-dicyanoketones by one-pot three-component reaction of phenylglyoxals, indoles and
malononitrile. The synthetic utility of obtained indole substituted β,β-dicyanoketones has been outlined
by the preparation of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles. The advantage of
catalyst-free, atom-economical and environmental benignity render it promising methods for preparation
of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles.

Abstract
A nanocomposite of polyaniline with graphitic carbon nitride (GCN) nanosheets has been synthesized by a facile oxidative polymerization of an aniline monomer and GCN to demonstrate its potential to catalyze the synthesis of various indole-substituted 4H-chromenes. The synthesized nanocomposite was thoroughly characterized using different spectroscopic techniques to confirm the morphology and composition. Subsequently, the fabricated nanocomposite was used as a heterogeneous catalyst to synthesize several bioactive indole-substituted 4H-chromenes in an aqueous medium. Organic transformation under benign and environmentally sustainable conditions is of paramount importance in the view of growing environmental pollution. Water is the universal Green solvent and has been a preferred choice of nature to perform various reactions. The catalyst developed in this work showed very good recyclability and adaptability for the synthesis of various medicinally significant indole-substituted 4H-chromenes. This multicomponent reaction imparts very high atom economy (94%) and low environmental factor (0.13).

Abstract
The preparation of sixteen 3-substituted indoles in good to excellent yields under environmentally friendly conditions has been achieved via a three-component reaction in water of an indole, an aldehyde and malononitrile (or ethyl 2-cyanoacetate) catalysed by 5 mol% of 2-pyrrolecarbaldiminato-Cu(II).

Abstract
EDDF–ethylene glycol, an ambiphilic catalytic system has been employed for the mild and rapid synthesis of various 3-indolochromenes and 3-indoloxanthenesviaa one-pot MCR. Besides recyclability of the catalyst, the present method circumvents the formation of any by-products.
