The first synthesis of (Z)-neomanoalide (4) and an improved synthesis of its (E)-isomer 3 was accomplished in a concise, regiocontrolled manner by exploiting 2-[(tert-butyl)dimethylsiloxy]-4[(tert-butyl)dimethylsiloxy]-methyl}furan (6) as the key reagent. Lithiation of 6 and subsequent reaction with the (2Z)- or (2E)-isomer of (6E)-3-[(tert-butyl)dimethylsiloxy]methyl}-7-methyl-9-(2′,6′,6′-trime
(第一合成Ž)-neomanoalide(4)和它的(的改进的合成ë) -异构体3是由利用2以简洁实现,regiocontrolled方式- [(叔丁基)二甲基甲硅烷] -4 - [(叔-丁基)二甲基甲硅烷氧基]-甲基}呋喃(6)作为关键试剂。6的锂化和随后与(6 E)-3-[((叔丁基)二甲基甲硅烷氧基]甲基} -7-甲基-9-(2' )的(2 Z)-或(2 E)异构体反应, 6',6'-三甲基环己-1'-烯基)壬基-2,6-二烯基溴化物(5),然后水解,得到相应的新马来酰亚胺。
