The investigation of the effect of the cyclopentane ring on the regiochemistry of the reactions of 2-acetylcyclopentanones 1a-d and β-methoxyvinyl trifluoromethyl ketone derivative 2a with hydroxylamine hydrochloride is reported. The reactions give regiospecifically the 4,5-trimethylene-4,5-dihydroisoxazoles 3a-d in good yields.
据报道,研究了环戊烷环对2-乙酰基环戊酮1a-d和β-甲氧基乙烯基三氟甲基酮衍生物2a与羟胺盐酸盐反应的区域化学的影响。该反应以良好的产率以区域特异性方式得到4,5-三亚甲基-4,5-二氢异恶唑3a-d。
