A concise approach to a gelsemine core structure using an oxygen to carbon bridge swapping strategy

Org Lett. 2008 Nov 6;10(21):4747-50. doi: 10.1021/ol801835q. Epub 2008 Oct 7.

Abstract

A tricyclic core structure 2 related to gelsemine 1 was synthesized from an oxabicyclo[3.2.1]octanone 4 by a three-step bridge swapping strategy involving elimination of the bridging ether oxygen and intramolecular Michael addition of a tethered cyanoacetamide unit.
