The stereostructures of some condensed-skeleton cis- and trans-dihydro-1,3-thiazines and 1-thia-2-phenyl-3-azaspiroalk-2-enes (n = 3-6) were established by 1H and 13C NMR spectroscopy.A comparative study indicated that the cis-thiazines have greater

cis- and trans-4,5-Tetramethylene-4,5-dihydro-6H-1,3-thiazines (2) were synthesized by heating the corresponding oxazines (1) with phosphorus pentasulfide.In the case of the 5,6-polymethylene analogues, trans-1,3-thiazines (4) were obtained from cis-1,3-o
