A masked lithium homoenolate, generated by tellurium/lithium exchange, was reacted with epoxides. The lithium compound was also converted into other organometallics such as Grignard, and cuprates and the reactivity of those organometallics with epoxides was evaluated. The same building block was employed in the synthesis of (+/−)-frontalin.
通过碲/锂交换产生的被掩盖的均烯酸锂与环氧化物反应。锂化合物也被转化为其他有机金属,例如格利雅(Grignard),并评估了铜酸盐和这些有机金属与环氧化物的反应性。在(+/-)-额叶蛋白的合成中使用了相同的结构单元。
