following dissadvan-tages: harsh reaction conditions, long reaction times, low yields, use of corrosive, expensive or moisture-sensitive reagents, destruction of the catalyst in work-up procedure, special efforts require to prepare the catalysts and tedious work-up procedure. Therefore, there is a scope to develop an alternative method for the protection of aldehydes as 1,3-oxathiolanes.In recent years,
然而,这些程序中的许多都具有以下一个或多个缺点:苛刻的反应条件、反应时间长、产率低、使用腐蚀性、昂贵或对水分敏感的试剂、在后处理过程中破坏催化剂,需要特别努力来准备催化剂和繁琐的后处理程序。因此,开发一种替代方法来保护醛类作为1,3-氧杂硫杂环戊烷是有空间的。近年来,引入用于官能团转化的新试剂,成为我们研究计划的重要组成部分。
