Lactam studies XVIII. Lactim ethers of 3,4-dihydrocarbostyril and benz (1,4)thiazanone-3 in reaction with α-amino-α-cyanoacetamide, and synthesis of derivatives of purino (8, 9-a)quinoline and benz (1,4) thiazano-(3,4-e)purine

of the trends in the search for biologically active substances based on lactams is the synthesis of 8,9-condensed purines, which is based in the general case on the react ion of laetim ethers with s a m i n o ~-cyanoacetamide (I) in the p resence of hydrogen chloride and subsequent c losure of the pyrimidine ring [1]. In the presen t investigation, the lact im ethers of 3 ,4-d ihydrocarbos tyr i l (If)
寻找基于内酰胺的生物活性物质的趋势之一是合成 8,9-缩合嘌呤,这在一般情况下是基于 Laetim 醚与 p 中的 samino ~-氰基乙酰胺 (I) 的反应。氯化氢的存在和随后的嘧啶环闭合 [1]。在目前的研究中,为此目的选择了 3,4-二二烃基酪氨酸 (If) 和苯 (1,4)thiazanone-3 (III) 的乳酯;从这些我们提议合成新的杂环系统的衍生物:嘌呤(8,9-a)-喹啉和苯(1,4)噻氮杂(3,4-e)嘌呤。
