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 and . The approach is based on a dual stereocontrol in the 1,4-functionalization of conjugated dienes. ... 6-Benzyloxy-1,3-cycloheptadiene was transformed to pseudotropine and tropine derivatives in a stereocontrolled manner. ...
