An efficient and convenient protocol has been developed for ether bond formation in mild conditions. A mixture of primary/secondary ester and allylic/benzylic halide in tetrahydrofuran was treated with KOtBu at room temperature to give ether in high yield. This step economic method enabled direct alkylation of the acyl group masked O-nucleophiles. Application of this method in carbohydrate synthesis
已经开发出一种有效且方便的方案,用于在温和条件下形成醚键。在室温下用KO t Bu处理伯/仲酯和烯丙基/苄基卤化物在四氢呋喃中的混合物,以高收率得到醚。此步骤的经济方法使酰基掩蔽的O-亲核试剂能够直接烷基化。该方法在碳水化合物合成中的应用是可行的,并且可以实现化学选择性。
