Abstract: An enantioselective intermolecular carbonyl–ene reaction and a Friedel–Crafts-type reaction of 1,1,2-trisubstituted and 1,2-disubstituted simple olefins with ethyl glyoxylate were developed using F10BINOL-derived N-sulfonyl phosphoramide as the chiral strong Bronsted acid catalyst. The present reactions feature… read more here.

Abstract: In this review, we discuss Friedel-Crafts-type aromatic amidation and acylation reactions, not exhaustively, but mainly based on our research results. The electrophilic species involved are isocyanate cation and acylium cation, respectively, and both have a… read more here.
