2-Methylimino-1,3-oxathiolanes 3, readily obtained from lithiated S,S'-dialkyl N-(methyl)imidodithiocarbonates 1 and carbonyl compounds 2, were transformed into thiiranes 6 via N,N-dimethyl-N-(1,3-oxathiolan-2-ylidene)ammonium iodides 7.With exclusion of 5-aryl-substituted compounds 3 the reaction proceeds highly diastereoselectively.
