✦ Synopsis

The stereoespecific syntheses of cis-and trans-2,3-dimethyl-1,4-oxathian, their diastereomeric --. S-oxides and their S-dioxide derivatives are reported. The key step in the synthetic pathways is the cyclization ofa 2-hydroxyalkyl vinylsulphoxide, by intramolecular conjugated addition with retention of configuration in the C and S chiral centers.
