new approach has been demonstrated for the regiospecific aldol synthesis by the simultaneous addition of α-halo carbonyl derivatives and aldehydes or ketones to a suspension of diethylaluminum chloride and zinc in tetrahydrofuran at low temperature. This technique is also employable under mild conditions for the Reformatsky reaction to give β-hiydroxy esters in excellent yield. One of the unique synthetic
通过在低温下将 α-卤代羰基衍生物和醛或酮同时添加到二乙基氯化铝和锌在四氢呋喃中的悬浮液中,已经证明了一种用于区域特异性羟醛合成的新方法。该技术也可在温和条件下用于 Reformatsky 反应,以优异的产率得到 β-羟基酯。ω-羟基醛的α-溴酯的分子内环化说明了该方法的独特合成应用之一,该环化产生大环内酯类,这是抗生素领域的一类重要化合物。
