The preparation of 2- and 2,3-substituted 5,6-dihydro-1,4-oxathiines has been studied by computer simulation and by experiment.Three major synthetic pathways, involving 2-(1-hydroxyalkyl)-1,3-oxathiolanes, 2-(1-haloalkyl)-1,3-oxathiolanes, 2-hydroxyethylthiomethyl ketones, methanesulfonates of 2-hydroxyethylthiomethyl ketones and 2-choroethylthiomethyl ketones as intermediates, were evaluated, by running the program CAMEO, and by experiment.The results of the two approaches were compared and the major by-products of the reactions were identified by GLC/MS.
