Abstract: Cyanacetohydrazide, protected at the nitrogen atom of hydrazide group, underwent cyclocondensation by Ritter reaction with 3,3-dialkylbenzylcarbinols, forming 3,3-dialkyl-1,2,3,4-tetrahydroisoquinolines. The reagents used for the protection of hydrazide group were benzaldehyde, benzoyl chloride, phenyl isocyanate, and phenyl… read more here.
