Direct methoxypyridine functionalization approach to magellanine-type Lycopodium alkaloids

Org Lett. 2012 Jan 20;14(2):632-5. doi: 10.1021/ol203269f. Epub 2011 Dec 27.

Abstract

A concise enantioselective approach to the tetracyclic core of the magellanine-type Lycopodium alkaloids is reported. Key to this approach is the use of the Hajos-Parrish reaction to set a challenging quaternary stereocenter, thereby guiding the stereoselectivity for the remainder of the synthesis, as well as the use of a palladium-mediated direct pyridine functionalization reaction to forge the tetracyclic core.
