Deprotonation of allyl chlorides 1 and 8 with lithium diisopropylamide (LDA) gives chlorocinnamyllithium 2 and benzothiazolylchloroallyllithium 9. Both 2 and 9 react with unenolizable carbonyl compounds with the in situ quench procedure furnishing styryl oxiranes 7 and benzothiazolylvinyl oxiranes 10. In the absence of an external electrophile, 2 undergoes a homocoupling reaction leading to the enyne
用二异丙基氨基锂(LDA)对烯丙基氯1和8进行质子化,得到氯肉桂基锂2和苯并噻唑基氯烯丙基锂9。既2和9与该unenolizable羰基化合物反应就地淬火过程家具苯乙烯基环氧乙烷7和benzothiazolylvinyl环氧乙烷10。在不存在外部亲电试剂的情况下,2发生均偶联反应,从而导致烯炔5。1的锂化,然后添加羰基化合物,提供炔丙醇6。
