A synthetic strategy to obtain a series of 3-heteroalkyl-4,5-dihydroisoxazoles, which is based on the cyclocondensation reaction of 5-heteroalkyl-1,1,1-trichloro-4-methoxy-3-penten[hexen]-2-ones 1a-g, 2a-g with hydroxylamine has been developed. The preparation of 1,1,1-trichloro-5-heteroalkyl-4-methoxy-3-penten[hexen]-2-ones in good yields is also described.
本研究基于 5-杂烷基-1,1,1-三氯-4-甲氧基-3-戊烯并[己烯]-2-酮 1a-g、2a-g 与羟胺的环缩合反应,开发了一种获得一系列 3-杂烷基-4,5-二氢异噁唑的合成策略。此外,还描述了以良好收率制备 1,1,1-三氯-5-异烷基-4-甲氧基-3-戊烯并[己烯]-2-酮的方法。
