A chiral Brønsted acid-catalyzed highly enantioselective Mannich-type reaction of α-diazo esters with in situ generated N-acyl ketimines

Rajshekhar A. Unhale, +5 more
- 03 Apr 2018 - 
TL;DR: A chiral phosphoric acid-catalyzed asymmetric Mannich-type reaction of α-diazo esters with in situ generated N-acyl ketimines, derived from 3-hydroxyisoindolinones has been demonstrated and the synthetic utility of the products has been depicted by the hydrogenation of the diazo moiety of adducts.
Journal ArticleDOI

Chiral phosphoric acid catalyzed enantioselective addition of thiols to in situ generated ketimines: Synthesis of N,S-ketals

Rajshekhar A. Unhale, +6 more
- 11 Jan 2017 - 
TL;DR: The chiral Bronsted acid catalyzed enantioselective 1,2-addition of thiols to in situ generated ketimines, derived from 3-hydroxyisoindolinones, has been studied and has been converted to a known non-nucleoside HIV-1 reverse transcriptase inhibitor and a 1,3-thiazine derivative.
Journal ArticleDOI

Synthesis of versatile intermediates for cyclopentanoid natural products via enantioselective deprotonation of substituted cyclopentene oxide

Debnath Bhuniya, +2 more
- 17 Apr 1995 - 
TL;DR: In this article, the anti-selective deprotonation of cis and trans-3,4-epoxycyclopentan-1-ol derivatives with phenylglycine based ligand (R)-5 was studied.
Journal ArticleDOI

Debnath Bhuniya, +1 more
- 01 May 1994 - 
TL;DR: In this article, the reaction of cyclohexene oxide with homochiral lithium amides, prepared from (S)-phenylglycine and (S)valine has been studied and (R)-2-cyclohexen-1-ol 3 was prepared in a maximum of 72% ee.
