An efficient method for generation of alpha-lambda3-iodanyl ketones from (Z)-(2-acetoxyvinyl)(phenyl)-lambda3-iodanes was developed. The method involves ester exchange of (Z)-2-acetoxyvinyl-lambda3-iodanes with methanol in the presence of triethylamine. alpha-lambda3-Iodanyl ketones react with a variety of nucleophiles such as halides, thiols, phosphines, phosphinic acids, and phosphates, under the
开发了一种从(Z)-(2-乙酰氧基乙烯基)(苯基)-λ3-碘酮生成α-λ3-碘酮的有效方法。该方法包括在三乙胺存在下,将(Z)-2-乙酰氧基乙烯基-λ3-碘酮与甲醇进行酯交换。在可能通过S(N)2途径产生α-官能化羰基化合物的条件下,α-lambda3-碘烷基酮会与各种亲核试剂发生反应,例如卤化物,硫醇,膦,次膦酸和磷酸盐。
