Synthesis of 1,3-thiazetidines and 2,1,4-oxathiazolidines by high yielding novel photochemical rearrangements
Abstract
The 1,3-thiazetidines 3, 6 and 9 have been prepared in good yield by photochemical rearrangement of the corresponding 1,3-thiazines and the rare fused 2,1,4-oxathiazolidines 12 and 17 have been prepared in good yield by photochemical rearrangement of the corresponding 1,3-thiazine sulfoxides
