Abstract

Abstract This invention is concerened with tetrahydropyrimidinyl phenyl carbonyl acid addition salts, imidazolinyl phenyl carbonyl acid addition salts, dihydroimidazoisoindolols, tetrahydropyrimidoisoindolols, and tetrahydropyrimidoisoindolol acid addition salts which are all pharmacologically efficacious as anti-depressants. The tetrahydropyrimidinyl phenyl carbonyl acid addition salts, the tetrahydropyrimidoisoindolols and the tetrahydropyrimidoisoindolol acid addition salts are also efficacious as diuretics while the imidazolinyl phenyl carbonyl acid addition salts and the dihydroimidazoisoindolols are effficacious as anorexiants. This invention is also concerned with several processes for the preparation of these compounds.
