STEREOCONTROLLED SYNTHESIS OF TROPANOL DERIVATIVES VIA PALLADIUM-CATALYZED REACTIONS

Baeckvall, J. E.,Renko, Z. D.,Bystroem, S. E.

, p. 4199 - 4202 (2007/10/02)

A general method for the transformation of 1,3-cycloheptadienes to tropane alkaloid derivatives was developed.The procedure was applied to the stereocontrolled synthesis of the exo- and endo-tropanol derivatives 1 and 2.The approach is based on a dual stereocontrol in the 1,4-functionalization of conjugated dienes.
