efficient and eco-friendly protocol has been developed for the preparation of n-alkyl terminal halohydrin esters under solvent- and catalyst-free conditions. Ring opening of cyclic ethers by organic acid halides affords the 1,4- and 1,5-halohydrins, OH-protected by different acyl groups. The green reaction conditions, simple work-up procedures, high yields and broad substrate scope of the reaction highlight
已经开发了一种有效且环保的方案,用于在无溶剂和无催化剂的条件下制备正烷基末端卤代醇酯。通过有机酰卤将环状醚开环,得到1,4-和1,5-卤代醇,由不同的酰基进行OH保护。绿色的反应条件,简单的后处理程序,高收率和反应的底物范围广,突出了该方法的积极特性。
