Substituted biphenyl-2-carboxaldehydes are prepared in good yield by reacting palladium complexes of substituted benzaldehyde aniline Schiff bases with substituted phenylmagnesium bromides in the presence of at least six, preferably eight, molar equivalents of triphenylphosphine. Those compounds are intermediates for synthetic, in vivo cholesterol synthesis inhibitors.
在至少 6 个摩尔当量(最好是 8 个摩尔当量)三苯基膦的存在下,取代苯甲醛苯胺希夫碱的钯络合物与取代苯基溴化镁反应,可以制备出产率很高的取代联苯-2-甲醛。这些化合物是合成体内胆固醇合成抑制剂的中间体。
