approach for the synthesis of functionalized unsymmetrical 1,3-butadiene-3-yne derivatives is reported starting from β-halo styrene and phenyl acetylene derivatives in the presence of PdCl2 and CuI catalysts. Functional groups such as aldehyde, cyano and ester groups are well tolerated and afford the desired functionalized dienynes. Further, these 1,3-buta-diene-3-yne derivatives are utilized for the
据报道,在PdCl 2和CuI催化剂存在下,从β-卤代苯乙烯和苯基乙炔衍生物开始合成官能化的不对称1,3-丁二烯-3-炔衍生物的方法。诸如醛基,氰基和酯基的官能团具有良好的耐受性,并提供所需的官能化二烯。此外,这些1,3-丁二烯-3-炔衍生物被用于合成新的三取代的吡啶衍生物。
