3-halo-2-propene-1-ols 13 by utilizing combinations of the Sonogashira coupling, allylation, and the Dess−Martin oxidation. The RCEM/dehydration for the synthesis of 1,3,5-tris(1-phenylethenyl)benzene derivative 4r and the RCEM/RCM/dehydration for the synthesis of 1,1′-binaphthyl derivative 19a are also presented as applications of this method.
报道了取代的碳环芳族化合物的一般合成方法。1,5-辛二烯-7-yn-4-ols 6的闭环烯炔复分解(RCEM)/脱水和1,5-辛二烯-7-yn-4-ones 7的RCEM /互变异构提供了多种取代基分别为苯乙烯4和4-乙烯基苯酚8。通过使用Sonogashira偶联,烯丙基化和Dess-Martin氧化的组合,可以轻松地从β-卤代-α,β-不饱和醛9或3-卤代-2-丙烯-1-醇13制备无环前体6和7。RCEM /脱水法合成1,3,5-三(1-苯基乙烯基)苯衍生物4r作为该方法的应用,还提出了用于合成1,1'-联萘衍生物19a的RCEM / RCM /脱水方法。
