2-addition reaction of 2,3-allenoates with allyl magnesium chloride at room temperature in the absence of any transition metal catalyst provides an efficient method for the synthesis of tertiary alpha-allenols. The optically active allenol could be prepared from the reaction of the optically active 2,3-allenoate without obvious racemization of the axial chirality. Under different reaction conditions
在本文中,据报道,在室温下,在不存在任何过渡金属催化剂的情况下,2,3-烯丙酸酯与烯丙基氯化镁的双1,2-加成反应为合成叔α-烯醇提供了一种有效的方法。旋光性烯丙醇可以由旋光性2,3-烯丙酸酯的反应制备,而没有明显的轴向手性外消旋化。在不同的反应条件下,已经研究了制备的α-烯醇2i的环化反应以合成不同的2,5-二氢呋喃衍生物。
