An efficient synthesis of the four isomeric epoxides 4aâd,
key compounds to the trinem ring system, starting from
(3R,4R,1â²R)-(+)-4-acetoxy-3-[1â²-
(tert-butyldimethylsilyloxy)ethyl]azetidin-2-one 6a is
described. All the intermediates have been characterized by means of NMR
techniques.
描述了一种高效合成四种异构体环氧化合物4a–d的过程,这些化合物是三烯环系统的关键化合物,起始于(3R,4R,1′R)-(+)-4-乙酰氧基-3-[1′-(叔丁基二甲基硅氧基)乙基]氮杂环己酮6a。所有中间体均通过NMR技术进行了表征。
