Journal ArticleDOI
Generation of Nitrile Oxides under Nanometer Micelles Built in Neutral Aqueous Media: Synthesis of Novel Glycal-Based Chiral Synthons and Optically Pure 2,8-Dioxabicyclo[4.4.0]decene Core
TL;DR: A highly efficient strategy for chemoselective oxidation of aldoximes to nitrile oxides by iodosobenzene in neutral aqueous media is reported.
Journal ArticleDOI
Synthesis of glycal-based chiral benzimidazoles by VO(acac)2-CeCl3 combo catalyst and their self-aggregated nanostructured materials.
Dilip K. Maiti,Samiran Halder,Palash Pandit,Nirbhik Chatterjee,Dripta De Joarder,Nabyendu Pramanik,Yasmin Saima,Amarendra Patra,P.K. Maiti +8 more
TL;DR: Theoretical calculation by the B3LYP/6-31G** level of theory of the glycal-based chiral benzimidazoles shows out of planar geometry of the 1H-anthra[1,2-d]imidrazole-6,11-dione moiety, which is responsible for the strong self-aggregation to generate ultralong nanostructured materials.
Journal ArticleDOI
PhIO as a powerful cyclizing reagent: regiospecific [3+2]-tandem oxidative cyclization of imine toward cofacially self-aggregated low molecular mass organic materials.
Palash Pandit,Nirbhik Chatterjee,Samiran Halder,Sandip K. Hota,Amarendra Patra,Dilip K. Maiti +5 more
TL;DR: The powerful cyclization and tandem oxidation property of environmentally benign PhIO is developed for the first time, which leads to regiospecific [3+2]-tandem oxidative cyclization of imine at room temperature in rapid access to a new class of compounds, 1,2-functionalized 4,5-diarylimidazoles, in excellent yield with synthetic efficiency.

TL;DR: In this article, an operationally simple protocol for the synthesis of a wide range of chiral benzimidazoles in high yields without formation of undesired 1,2-disubstituted and pseudoglycal byproducts is presented.
