T. Dalati et al., ELECTROREDUCTION OF 1,3-THIAZIN-6-ONES - AN EASY ROUTE TO 4,5-DIFUNCTIONALIZED 3-HYDROXY-1H-PYRROLES, Journal of chemical research. Synopses, (7), 1993, pp. 282-283
4,5-Disubstituted 3-hydroxy-1H-pyrroles have been selectively obtained
by controlled-potential electroreduction of substituted 1,3-thiazin-6
-ones, in protic medium, according to a reductive cyclic regression wi
th elimination of hydrogen sulfide.
