Alkylation of Heterocyclic Ketene Aminals with Benzyl Chloride and Ethyl Bromoacetate. Synthesis of Heterobicycles Containing γ-Lactam Fused Diazaheterocycles

Huang, Zhi-tang,Liu, Zhi-rong

, p. 95 - 100 (2007/10/02)

Heterocyclic ketene aminals 1 - 3 react with benzyl chloride to give the benzyl-substituted compounds 4 - 6.With ethyl bromoacetate, 1 - 3 react smoothly, and γ-lactam-fused heterobicycles 9 - 11 are obtained by further cyclocondensation of the alkylation products. - Keywords: Diazaheterocycles, γ-lactam-fused / Ketene aminals, heterocyclic
