摘要

The alkaloids (±)-hygrine,(±)-dehydrodarlinine,(±)-dehydrodarlingianine, and (±)-N- methylruspolinone have been synthesised by selective reduction of vinylogous amides formed by sulphide contraction of the salts prepared by reaction of N-methyl-2- thiopyrrolidone with the appropriate bromomethyl ketones.
