A general method for the preparation of acetylenedicarboxylic acid esters has been investigated and several esters have been prepared in excellent yield. The bis-(methyl (S)-lactyl), bis-(methyl (R)-mandelyl), and bis-menthyl esters were prepared, as well as achiral diaryl and dialkyl esters. The esters were synthesized from the corresponding dibromofumarates by 2,3-dibromo elimination using zinc or
已经研究了制备乙炔二羧酸酯的通用方法,并且已经以优异的产率制备了几种酯。制备了双-(甲基(S)-乳糖基),双-(甲基(R)-扁桃基)和双薄荷基酯,以及非手性二芳基和二烷基酯。通过在室温或回流下,使用锌或锌汞齐在THF中的2,3-二溴消除反应,由相应的二溴富马酸酯合成酯。通过将二溴富马酰氯与相应的醇酯化来制备二溴富马酸酯。
