Abstract
We report the visible-light-induced in situ preparation of COCl2 through the oxygenation of chloroform in the presence of chlorine dioxide, which leads to the safe constructions of carbamoyl chlorides with good-to-high yields and wide substrate scopes. In addition, this method can also be applied to the synthesis of various carbonates.

Abstract
An efficient and straightforward synthesis of polysubstituted oxazol-2(3H)-ones has been developed via a tandem Hofmann-type rearrangement and cyclization reaction of various α-acyl-β-aminoacrylamides mediated by phenyl iodine(III) bis(trifluoroacetate) (PIFA) in the presence of trifloroacetic acid (TFA). This novel protocol features readily available starting materials, mild reaction conditions, simple execution, high chemoselectivity, good functional group tolerance, and a metal-free oxidation process.

Abstract
Cancer, which has been cursed for human beings for long time is considered as one of the
leading causes of morbidity and mortality across the world. In spite of different types of treatments
available, chemotherapy is still deemed as a favored treatment for the cancer. Unfortunately, many currently
accessible anticancer agents have developed multidrug resistance along with fatal adverse effects.
Therefore, intensive efforts have been made to seek for new active drugs with improved anticancer efficacy
and reduced adverse effects. In recent years, the emergence of heterocyclic ring-containing anticancer
agents has gained a great deal of attention among medicinal chemists. 1,3- oxazole is a versatile
heterocyclic compound, and its derivatives possess broad-spectrum pharmacological properties, including
anticancer activity against both drug-susceptible, drug-resistant and even multidrug-resistant cancer
cell lines through multiple mechanisms. Thus, the 1,3-oxazole moiety is a useful template for the development
of novel anticancer agents. This review will provide a comprehensive overview of the recent
advances on 1,3-oxazole derivatives with potential therapeutic applications as anticancer agents, focus
on the chemical structures, anticancer activity, and mechanisms of action.

Synthesis, DNA binding and in-vitro cytotoxicity studies on novel bis-pyrazoles. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2017; 168:89-97.

Abstract
A new series of bis-pyrazoles 6a-t were synthesized from 3,5-dimethyl pyrazole using sequential approach. All these compounds were characterized by IR, 1H NMR, 13C NMR and mass spectral data. The interaction of newly synthesized bis-pyrazoles with DNA was investigated through molecular docking and absorption spectroscopic technique. Among all bis-pyrazoles compounds, the 6h compound showed lower conformational energy through in silico analysis. The interaction of each molecule in this series 6a-t with the various concentrations of DNA was examined through the UV-visible spectroscopic studies. The UV-visible spectroscopy studies on the specific binding of compound 6a, 6b, 6g, 6h, 6d, 6i, 6k, 6n, 6s with DNA have exhibited spectral shifts and the results were discussed. In further the compounds 6a-t were subjected to the in-vitro cytotoxicity studies against human pancreatic adenocarcinoma, human non-small cell lung carcinoma cell lines. Among the screened compounds, N-(3-isopropoxy-1-isopropyl-4-(3,5-dimethyl-1H-pyrazol-1-yl)-1H-pyrazol-5-yl)cyclobutane carboxamide and N-(5'-Isopropoxy-2'-isopropyl-3,5-dimethyl-2'H-[1,4'] bipyrazolyl-3'-yl)-dimethane sulfonamide were found as lead molecules since they have exhibited promising activity against both the cancer cell lines used in this study, whereas the compounds 4-(trifluoromethyl)-N-(3-isopropoxy-1-isopropyl-4-(3,5-dimethyl-2H-pyrrol-2-yl)-1H-pyrazol-5-yl)benzamide and 2,6-difluoro-N-(3-isopropoxy-1-isopropyl-4-(3,5-dimethyl-2H-pyrrol-2-yl)-1H-pyrazol-5-yl) benzamide were found to be active against the pancreatic cell line only. Rest all the other compounds were found to exhibit moderate to good activity towards both the cell lines.
