Stereoselective synthesis of 3-aryloctahydroindoles and application in a formal synthesis of (-)-pancracine

Org Lett. 2010 Feb 5;12(3):556-9. doi: 10.1021/ol902761a.

Abstract

A stereoselective synthesis of 3-aryloctahydroindoles from enantiomerically enriched gamma-nitroketones has been developed. Reduction of imines derived form the nitroketones provides the trans-fused octhaydroindole motif selectively. The cis-octahydroindole skeleton is accessible by an invertive cyclization strategy involving a diastereomerically pure nitromesylate intermediate. This approach was employed in the synthesis of an advanced intermediate to (-)-pancracine. The gamma-nitroketone starting materials are readily available via an organocatalytic Michael reaction.
