Abstract

The reactivity of mucochloric acid and its 5-substituted derivatives towards 2,2'-oxydiethanethiol was studied. A specific feature of the reaction of mucochloric acid with 2,2'-oxydiethanethiol carried out in the presence of triethylamine was revealed. Compared to previously studied reactions with aliphatic dithiols, minor products of the lactone ring degradation, possessing a propenal fragment, were also isolated in this reaction, along with a bis-thioether of the 2(5H)-furanone series. A series of novel bis-thioethers and thiols containing an unsaturated γ-lactone ring and a dithiol fragment were synthesized and characterized.
