Synthesis of 2-oxindoles via 'transition-metal-free' intramolecular dehydrogenative coupling (IDC) of sp2 C–H and sp3 C–H bonds
Autor: Nivesh Kumar, Santanu Ghosh, Subhajit Bhunia, Alakesh Bisai
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 12, Iss 1, Pp 1153-1169 (2016)
The synthesis of a variety of 2-oxindoles bearing an all-carbon quaternary center at the pseudo benzylic position has been achieved via a ‘transition-metal-free’ intramolecular dehydrogenative coupling (IDC). The construction of 2-oxindole moieti

Autor: Subhajit Bhunia, Pranay Saha, Parikshit Moitra, Matthew A. Addicoat, Santanu Bhattacharya
Publikováno v: Chemical Science. 13:7920-7932
Solid porous and crystalline covalent organic frameworks (COFs) are characterized by their higher specific BET surface areas and functional pore walls, which allow the adsorption of various bioactive molecules inside the porous lattices. We have intr

Catalytic asymmetric formal total syntheses of (+)- and (−)-cycloclavine
Autor: Santanu Ghosh, Alakesh Bisai, Saikat Chaudhuri, Subhajit Bhunia
Publikováno v: Chemical Communications. 54:940-943
We report an expeditious catalytic asymmetric approach to clavine alkaloids via a key Heck cyclization. This reaction sets the formation of vicinal stereocenters with excellent diastereoselectivity. Utilizing the aforementioned strategy, the formal t

N,N′-Bisoxalamides Enhance the Catalytic Activity in Cu-Catalyzed Coupling of (Hetero)Aryl Bromides with Anilines and Secondary Amines
Autor: Dawei Ma, S. Vijay Kumar, Subhajit Bhunia
Publikováno v: The Journal of Organic Chemistry. 82:12603-12612
N,N'-Bis(furan-2-ylmethyl)oxalamide (BFMO), an inexpensive and conveniently available bidentate ligand, is very effective for promoting Cu-catalyzed N-arylation of anilines and cyclic secondary amines. The method enables coupling of a broad range of

Discovery of N-(Naphthalen-1-yl)-N′-alkyl Oxalamide Ligands Enables Cu-Catalyzed Aryl Amination with High Turnovers
Autor: Lu Gan, Dawei Ma, Xia Shanghua, Jie Gao, Wang Kailiang, Subhajit Bhunia
Publikováno v: Organic Letters. 19:2809-2812
A class of N-(naphthalen-1-yl)-N′-alkyl oxalamides have been proven to be powerful ligands, making a coupling reaction of (hetero)aryl iodides with primary amines proceed at 50 °C with only 0.01 mol % of Cu2O and ligand as well as a coupling react
