A Co(ii)-catalyzed asymmetric ring opening reaction of spiro-epoxyoxindoles with allylboron

A Co(ii)/BOX-catalyzed asymmetric allylation of spiroepoxyoxindoles was developed, which is the first stereoconvergent allylation of epoxides, yielding chiral oxindoles bearing quaternary stereocenters.

Palladium/silver co-catalyzed syn-stereoselective asymmetric ring-opening reactions of azabenzonorbornadienes with amides

The first syn-stereoselective generation of 1,2-diamino dihydronaphthalene derivatives by asymmetric ring-opening reaction of azabenzonorbornadienes is reported.

Asymmetric ring-opening of cyclopropyl ketones with β-naphthols catalyzed by a chiral N,N′-dioxide–scandium(iii) complex

An efficient asymmetric ring-opening reaction of cyclopropyl ketones with 2-naphthols has been realized using a chiral N,N′-dioxide–ScIII complex catalyst. A variety of chiral β-naphthol derivatives were obtained in excellent outcomes (up to 99% yield, 97% ee).

The mechanism of an asymmetric ring-opening reaction of epoxide with amine catalyzed by a metal–organic framework: insights from combined quantum mechanics and molecular mechanics calculations

QM/MM computations suggest that the asymmetric ring-opening reaction of epoxide with amine is controlled by CH–π interactions between aniline and a naphthol moiety.
