Abstract
PURPOSE: To prepare 3-carbamoly-1,2-dihydro-4-hydroxy-5-methoxy-3H-[3,2-e] indole-7-carboxylic acid useful as an enzyme inhibitor, by chemical synthesis.
CONSTITUTION: The objective compound VIII is prepared by (1) protecting the 7- position OH group of compound I to obtain compound II; (2) converting the compound II to compound III by alkali hydrolysis; (3) converting the 1-position of the compound III to afford compound IV; (4) hydrogenating the compound IV; (5) converting the resulting compound V to compound VI by diazotization and reaction with ethyl-2-acetylpropionate; (6) cyclizing the compound VI to compound VII which is a derivative of 1,2-dihydro-3H-pyrrolo[3,2-e]indole; and finally (7) hydrolyzing the compound VII.
