A highly regio- and stereoselective Pd-catalyzed tandem allylic rearrangement/intramolecular decarboxylative coupling of aryl propiolates derived from Baylis–Hillman alcohols leading to the formation of an important class of 1,5-diarylpent-1-en-4-ynes has been developed. The aryl propiolates of Baylis–Hillman alcohols derived from methyl acrylate provided exclusively (E)-1,5-diarylpent-1-en-4-ynes
已经开发出高度区域选择性和立体选择性的Pd催化串联烯丙基重排/分子内脱羧的衍生自Baylis-Hillman醇的丙酸芳酯,导致形成一类重要的1,5-二芳基戊-1-烯-4-炔。丙烯酸甲酯衍生的Baylis–Hillman醇的芳基丙酸酯仅提供(E)-1,5-二芳基-1-en-4-ynes,而丙烯腈衍生的Baylis–Hillman醇的芳基丙酸酯仅提供(Z)-1 ,5-二芳基戊-1-烯-4-炔。
