Zinnes and co-workers prepared pyrido[l,2-b][l,2]benzothiazines (Scheme 8) 1,2-benzothiazine 182 with isopropyl iodide and potassium carbonate resulted in spontaneous aldol cyclization of the intermediate enol ether 183 to 7,8-dihydro-8-hydroxy-ll-isopropyloxy 8-substituted pyrido[l,2-b][l,2]benzothiazin-10(9//)-one 5,5 dioxide (184). In sulfuric acid, dehydration and ether cleavage of 184 gave the corresponding unsaturated )3-diketone 185. Hydrogenation gave the saturated analogs 186. An attempt to prepare 186 directly by base-catalyzed cyclization of 187 afforded a high yield of 2,3-dihydro-6/f-oxepino [3,2-c][l,2]benzothiazin-5(4H)-one 7,7-dioxide (188) (Eq. 39).
