Abstract
1-Aryl-3,4,5,6-tetrahydro-2-(1H)pyrimidinones (I) underwent reductive ring opening reaction with lithium aluminum hydride to afford N-aryl-2,4-diaminopentanes (II) in good yields. On the other hand, 3,4,5,6-tetrahydro-3,4,6-trimethyl-1-phenyl-2-(1H)-pyrimidinone (V) gave only cyclic diamine, 3,4,6-trimethyl-1-phenylhexahydropyrimidine (VI), in 60% yield.
