Journal ArticleDOI
Organocatalytic and electrophilic approach to oxindoles with C3-quaternary stereocenters.
TL;DR: A Lewis base-catalyzed asymmetric allylic alkylation of Morita-Baylis-Hillman carbonates derived from isatins has been investigated, which provides an electrophilic pathway to access oxindoles bearing C3-quaternary stereocenters.
Journal ArticleDOI
A designer axially chiral amino sulfonamide as an efficient organocatalyst for direct asymmetric anti-selective Mannich reactions and syn-selective cross-aldol reactions.
TL;DR: A direct asymmetric Mannich reaction using a novel axially chiral amino sulfonamide (S)-3 that is highly anti- and enantioselective has been developed and has also been successfully applied to asymmetric direct cross-aldol reaction between two different aldehydes.

TL;DR: A thermally activated delayed fluorescent (TADF) emitter using a rigid 9,9-dimethyl-9H-thioxanthene 10,10-dioxide (DMTD) acceptor and an acridine donor was developed in this article.
Journal ArticleDOI
Organocatalytic asymmetric intermolecular dehydrogenative α-alkylation of aldehydes using molecular oxygen as oxidant.
TL;DR: An organocatalytic enantioselective intermolecular oxidative dehydrogenative α-alkylation of aldehydes via benzylic C-H bond activation has been developed using simple and green molecular oxygen as the oxidant.
