A series of 4-alkylsulfonylmethy1 derivatives of 4-through an intermediate product which can be isolated thiazoline-2-thiones has been obtained by reaction of and has been shown to be a substituted 4-hydroxythiammonium dithiocarbamate and 1-alkylsulfonyl-3-a~ olidine-2- thione.~ In a subsequent step, dehydrabromo-2-propanones. This type of synthesis proceeds tion forms a 4-thiazoline ring. Required l-alkylsulfonyl-3-bromo-2-propanones ...
