然而，这些方法中的许多遭受以下缺点中的一个或多个：苛刻的反应条件、长的反应时间、低的产率、使用腐蚀性的、昂贵的或对湿气敏感的试剂、在后处理过程中催化剂的破坏、需要特别努力来制备催化剂和冗长的后处理过程。近年来，引入新的试剂进行功能基团的转化，成为我们研究的重要内容。
However, many of these procedures suffer from one or more of the 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, the introduction of new reagents for the func-tional group transformations, became an important part of our research program.
