Abstract

A method for preparing the fused cyclohexane and pyrrolidine portion of the strychnos skeleton has been developed using domino intermolecular and intramolecular SN2 cyclization. Using this method, the formation of pyrrolidine proceeded smoothly with good yield without the E2 elimination product. This reaction condition is effective for synthesizing the fused cyclohexane and pyrrolidine portion of the strychnos skeleton.
