Enantioselective total synthesis of (+)-testudinariol a using a new nickel-catalyzed allenyl aldehyde cyclization

J Am Chem Soc. 2002 Aug 14;124(32):9366-7. doi: 10.1021/ja027148y.

Abstract

An enantioselective total synthesis of (+)-testudinariol A was completed. A new nickel-catalyzed allenyl aldehyde cyclization was developed in the approach. In addition, an asymmetric anti aldol reaction and a two-directional oxocarbenium ion/vinyl silane condensation were employed as key steps.
