Abstract
Currently, amidst atmospheric menace where natural calamities such as wildfire and floods are becoming more frequent than ever, biobased derivatives offer a sustainable alternative to conventional ways, for instance, petrochemical commodities. Biobased products, obtained from agricultural waste, including 5-(hydroxymethyl)furfural (HMF), 2,5-bis(hydroxymethyl)furan (BHMF), and 2,5-furandicarboxylic acid (FDCA) are promising chemical platforms in the biorefinery, which is yet to be explored. The Diels-Alder cycloaddition of BHMF and N-phenylmaleimide derivatives under optimal reaction conditions is investigated in this report. First, HMF is reduced to BHMF in the presence of NaBH4, and then the Diels-Alder reaction of BHMF and N-phenylmaleimide derivatives is investigated to produce Diels-Alder adducts. All novel compounds are synthesized in acceptable yields and effectively characterized by employing important techniques such as one-dimensional (1D) NMR spectroscopy (1H, 13C, DEPT-90, and DEPT- 135), two-dimensional (2D) NMR spectroscopy (1H-1H COSY, 1H-13C HSQC, and 1H-13C HMBC), IR spectroscopy, elemental analysis, mass spectrum (QTOF), and single-crystal X-ray diffraction (SC-XRD). Furthermore, this study underlines the necessity of sustainable synthetic methodologies and gives critical insights into the progress of ecologically friendly methodologies, providing a new avenue as a tunable precursor for the challenging functionalized polymer in the future.

Abstract
![]()
The synthesis of calix[4]- and -[6]arene derivatives P6(H)22+·(Cl–)2, V4(H)24+·(Cl–)2·(I–)2, and V6(H)24+·(Cl–)2·(I–)2 bearing N-linked pyridinium (P) and viologen (V) units at the upper rim is described here. A rare example
of an anionic conformational template is reported for p-pyridiniumcalix[6]arene P6(H)22+, which adopts a 1,3,5-alternate conformation in the presence of
chloride anions. Derivatives P6(H)22+·(Cl–)2, V6(H)24+·(Cl–)2·(I–)2, and V4(H)24+·(Cl–)2·(I–)2 show a negative solvatochromism, while their UV–vis
acid–base titration evidenced that upon addition of a base,
new bands appear at 487, 583, and 686 nm, respectively, due to the
formation of betainic monodeprotonated species P6(H)1+, V6(H)13+,
and V4(H)13+. These new bands were
attributable to the intramolecular charge-transfer (CT) transition
from the phenoxide to the pyridinium or viologen moiety and were responsive
to the presence of cations. In fact, the band at 487 nm of P6(H)1+ was quenched in the presence of a hard
Li+ cation, and the color of its acetonitrile solution
was changed from pink to colorless upon addition of LiI. Consequently,
this derivative can be considered as a useful host for the recognition
and sensing of lithium cations.

Abstract
Since the dawn of supramolecular chemistry, calixarenes have been employed as platforms onto which functional groups and binding sites can be loaded in a regio- and stereocontrolled manner for the recognition of charged and neutral species. Despite their wider annulus, potentially suitable to bind larger guests, the larger members of the calixarene series have been relatively less employed, mainly because of the synthetic difficulties to control their conformational flexibility and their regioselective functionalization. In this account, we will present the achievements gained during the last two decades on the use of the calix[6]arene as a platform to build-up structures in which the macrocycle acts as a wheel for the synthesis of oriented (pseudo)rotaxanes. We also account on how these calix[6]arene hosts affect the reactivity or spectroscopic properties of their bound guests.
