摘要:
Eserethole of formula ##STR1## is prepared from 1,3-dimethyl-5-hydroxy-oxindole compound II which is acylated in the first step to obtain 1,3-dimethyl-5-acyloxyoxindole (III). The product is reacted with chloroacetonitrile to obtain 1,3-dimethyl-3-cyanomethyl-5-acyloxy-oxindole (IV). The 5-acyloxy group is hydrolyzed and the hydroxy group is ethoxylated with ethyl halides or sulfate. Then the product is cyclized by treatment with sodium bis-(methoxy-ethoxy)aluminum hydride, to give O-ethyl-nor-eseroline (VI) and the compound is methylated to give eserethole (VII).
