2-aryl-4-benzyl-5-methyloxazole N-oxides have been synthesized. It has been shown that the action of the POCl3 does not lead to the formation of the product of the known deoxygenation-chlorination reaction, but proceeds with the opening of the oxazole ring. As a result, a series of (Z)-N-(3-oxo-1-phenylbut-1-en-2-yl)arylamides was obtained with yields of 25–92%.
已经合成了几种 2-芳基-4-苄基-5-甲基
恶唑N-氧化物。已经表明,POCl 3 的作用不会导致已知脱氧-
氯化反应产物的形成,而是随着
恶唑环的打开而进行。结果,以25-92%的产率获得了一系列(Z)-N-(3-氧代-1-苯基丁-1-烯-2-基)芳基酰胺。
