1-(2-Substituted-hydrazino)-3,4-dihydroisoquinolines, prepared in one process by alkylating the corresponding 3,4-dihydroisocarbostyrils, hydrazinolyzing the resulting 1-alkoxy-3,4-dihydroisoquinolines and condensing the resulting 1-hydrazIno-3,4-dihydroisoquinolines with aldehydes or ketones, and 1,1'-azinobis(1,2,3,4-tetrahydroisoquinolines), prepared by condensing corresponding 1-alkoxy-3,4-dihydroisoquinolines and 1-hydrazino-3,4-dihydroisoquinolines, are useful as antihypertensive agents and/or as antiinflammatory agents.

step high yielding synthesis of a library of 14 chiral isoquinolinone and azepinone derivatives with benzyl, pyridyl and thiophene cores starting from amidoarylboronic acid aldehydes. These products have potential for treating neurodegenerative diseases. The key reaction in this synthetic pathway was an efficient metal-catalyzed (with Rh, Cu and Pd catalysts) intramolecular cyclization. A maximum yield
