synthesis are discussed. Substitution of the bromo nucleofug in the 2-position of 1,3-dicarbonyl compounds as well as of a 3-oxosulfone by selected sulfur nucleophiles is assumed to follow an SRN1 pathway. Characteristic properties, some typical reactions, and selected derivatives were studied. S-Alkyl- and S-aryl-substituted cyclic 2-thioreductones have been found to be synthons for the preparation of vinylogous
硫代还原酮及其衍生物。一个或两个(原则上也3)O-原子置换ACI -reductones通过硫通向相应thioreductones。在本文中,讨论了其合成的不同方法。假定溴硫代核糖在1,3-二羰基化合物的2位以及3-氧代砜中被选定的硫亲核试剂取代,遵循S RN 1途径。研究了特性,一些典型的反应和选择的衍生物。S-烷基和S已经发现,芳基取代的环状2-硫代还原酮是用于制备乙烯基类还原酮(2,3-二酰基-1,4-二羟基-1,3-二烯)和作为其双脱氢产物的四酰基乙烯的合成子。
