The reactions of benzo[e][2,1]thiazine-4-chloro-3-carbaldehydes 1 and benzo[e][2,1]thiazine-4-chloro-3-carbonitriles 2 with a number of oxidizing and reducing agents are reported. A number of new, highly functionalized benzo[e][2,1]thiazine derivatives having potential biological activity were synthesized and described.
A synthesis of N-alkyl-4-chloro-1H-benzo[c][1,2]thiazine-3-carbaldehyde-2,2-dioxides is described. Reactivity of new β-chloroaldehydes is investigated, a number of novel benzo[c][1,2]thiazine derivatives are synthesized and characterized using 1H, 13C-NMR, MS and elemental analysis.
