Abstract: | Novel tandem hydration of a-thiocyanatoketones to thiocarbamates followed by in situ cyclodehydration to fused 2-oxo-3-thiazolines is described. Concentrated sulfuric acid was found to be critical for the reaction as both corresponding thiocyanates and thiocarbamates rapidly hydrolyze in the presence of water. | ||||||||||
