3-(1-tert-Butyldimethylsiloxy)ethyl-4-sulfinylazetidin-2-one was reacted with silylated N-, S-, O-, and P-nucleophiles in the presence of a catalytic amount of ZnI2 to give the corresponding trans-4-heterofunction-substituted azetidin-2-ones in high yelids.
在催化量 ZnI2 的存在下,3-(1-叔丁基二甲基硅氧基)乙基-4-亚磺酰基氮杂环丁烷-2-酮与硅烷化的 N-、S-、O-和 P-亲核物发生反应,得到相应的反式-4-杂环丁烷-2-酮高倍率化合物。
