This Letter describes a versatile synthetic approach to prepare physovenine and physostigmine analogs. A series of analogs were synthesized and evaluated for cholinesterase inhibition activities, including human acetylcholinesterase (AChE) and butyrylchol

Olefin cross-metathesis between α-methylene-γ-butyrolactone and terminal olefins is described. Moderate to excellent yields of α-alkylidene-γ-butyrolactones were obtained with high E-stereoselectivity in the presence of low catalyst loading in refluxing CH 2Cl2. In addition, the use of various additives was found to have a dramatic effect on the efficiency of the cross-metathesis (CM) process by circumventing the formation of the isomerized byproduct.
