A selective copper (Cu)-catalyzed C–S bond direct cross-coupling of thiols with 5-arylpenta-2,4-dienoic acid ethyl ester was developed. Notably, various biologically active 5-phenyl-3-phenylsulfanylpenta-2,4-dienoic acid ethyl ester derivatives were efficiently synthesized under moderate conditions. Finally, a plausible Cu(I)/Cu(III) reaction mechanism was proposed.
开发了选择性铜 (Cu) 催化的 C-S 键直接交叉偶联硫醇与 5-arylpenta-2,4-二烯酸乙酯。值得注意的是,各种具有生物活性的 5-苯基-3-苯基硫烷基五-2,4-二烯酸乙酯衍生物在温和条件下被高效合成。最后,提出了一种似是而非的Cu( I )/Cu( III )反应机理。
