Novel method for transforming aldehydes and acetals into 1,3-dithianes has been achieved with the aid of organotin thioalkoxides and organotin triflates. Under these reaction conditions, various acid-sensitive groups are tolerated. Differentiation between aromatic or aliphatic aldehydes and acetals has been realized.
借助于
有机锡硫代醇盐和
有机锡三氟甲磺酸酯,已经实现了将醛和
乙缩醛转化为1,3-二
硫杂
环己烷的新方法。在这些反应条件下,可以耐受各种酸敏感性基团。已经实现了芳族或脂族醛与
缩醛之间的区分。
