AMINOPHTHALAZINONE DERIVATIVES, VII REACTION OF CHLOROPHTHALAZINONE WITH SECONDARY AMINES STUDY OF THE STERIC EFFECT, II

In the aminolysis of chlorophthalazinone (1a) with secondary amines, the yield of N-substitution (1 5, 1 7) is significantly affected by the steric structure of the amine.In the cyclic secondary amines substituents at the C-2 position give rise to a strong steric hindrance.The possibility for N-substitution gradually decreases with increasing size of the ring, while in the case of open-chain secondary amines it varies suddenly as a function of the position of the NH group in the chain.
