Abstract
The reaction of cis- and trans-4-alkoxycarbonylamino-3-hydroxythiophans with thionyl chloride gives chlorosulfites. trans-4-Alkoxycarbonylamino-3-chlorosulfito-thiophans are converted to cis-3a,4,6,6a-tetrahydrothieno[3,4-d]oxazolidone by heating or by treatment with pyridine. cis-4-Carboalkoxyamino-3-hydroxythiophans form 3-carboalkoxy-3a,4,6,6a-tetrahydrothieno[3,4-d]oxathiazolidones.
