Isoindolderivater, their preparation and use

摘要

Novel phthalimide intermediates are reduced to 5-sulfamoyl-6-halo-3-oxoisoindole compounds bearing a substituted 1-phenylalkyl-4-piperidinyl moiety as the isoindole N-substituent. Preferred compounds such as 6-chloro-2,3-dihydro-3-oxo-2-[1-(phenylmethyl)-4-piperidinyl]-1_H-isoi ndole-5-sulfonamide exhibit diuretic and antihypertensive properties.
