Asymmetric synthesis of cis-2-aminocyclopropanols by intramolecular Mannich addition of silyloxy benzyl carbanions.

Bo Liu1, Chong-Dao Lu.   

Abstract

An efficient, highly diastereoselective method for the preparation of protected cis-2-aminocyclopropanols from N-tert-butanesulfinyl ketimines and various aryl acylsilanes is described. A tandem process for carbon-carbon bond formation via nucleophilic addition to acylsilanes, Brook rearrangement, and intramolecular Mannich reaction has been developed.
