摘要：

Several new imidazo[2,1-b]-1,3-thiazine derivatives 4a-c, 8a-c, and 11a-c were synthesised via the reaction of 5,5-diphenyl-2-thiohydantoin (1) with alpha,beta-unsaturated nitriles 2a-c, 5a-c, and 9a-c. The structures of the products were established on the basis of elemental analyses, IR, and H-1-NMR spectral data.
