versatile synthesis of 3-alkyl- and 3-alkenyl-5-hydroxycyclopent-2-enones is described. The key intermediate, 4-(t-butyldimethylsilyloxy)-3-methoxycyclopent-2-enone (5), is prepared in five steps from phenol. 1,2-Addition of various organolithium and Grignard reagents yields tertiary alcohol intermediates which afford the title compounds after solvolysis and desilylation.
描述了3-烷基-和3-烯基-5-羟基环戊-2-烯酮的有效且通用的合成。关键中间体4-(叔丁基二甲基甲硅烷氧基)-3-甲氧基环戊-2-烯酮(5)由苯酚分五步制备。1,2-添加各种有机锂和格氏试剂产生叔醇中间体,其在溶剂化和去甲硅烷基化后提供标题化合物。
