An improved method for the preparation of intermediates of formula: ##EQU1## WHERE R.sup.1 and R.sup.2 represent hydrogen, C.sub.1.sub.-4 alkyl, C.sub.1.sub.-4 hydroxyalkyl, C.sub.3.sub.-10 cycloalkyl, C.sub.3.sub.-6 acyloxyalkyl, or phenyl, by mercuric ion assisted hydrolysis of the corresponding dithianes, and novel intermediates thereby produced.
一种改进的制备公式中间体的方法:##EQU1## 其中R.sup.1和R.sup.2代表氢,C.sub.1-4烷基,C.sub.1-4羟基烷基,C.sub.3-10环烷基,C.sub.3-6酰氧基烷基或苯基,通过汞离子辅助水解相应的二硫醚制备,并由此产生新的中间体。
