An efficient method has been found for the preparation of cyclic monodithioacetats of 1,3-dicarbonyl compounds usingborontrifluorideetherate as the acid catalyst. Asymmetric 1,3-diketones react regioselectively in most of the cases tried. A study of the 13C and 1H nmr characteristics of these compounds has been carried out.
已经发现使用三氟化硼醚化物作为酸催化剂来制备1,3-二羰基化合物的环状单二硫代乙酸酯的有效方法。在大多数尝试过的情况下,不对称的1,3-二酮会发生区域选择性反应。已经对这些化合物的13 C和1 H nmr特性进行了研究。
