A series of new substitutedbenzamides has been synthesized and evaluated for dopamine antagonist activity and for antagonism of cisplatin-induced emesis in the dog and in the ferret. It was found that modification of the 2-methoxy substituent of metoclopramide was detrimental to dopaminergic D2 antagonism but not necessarily to antagonism of cisplatin-induced emesis. A number of analogues having a

The vinyllithium reagent ()-, generated from the alkene by bromine/lithium exchange, reacts stereoselectively with prochiral carbonyl compounds. Debromination of the adducts / affords the ()-olefins /, which can be cleaved by ozonolysis.
