Abstract
The nucleophilic addition reactions of 4,5-diphenyl-1,2-thiazinylium perchl orate 1 regioselectively proceeded to give 6-alkoxy-3a-c and 6-alkyl-1,2-th iazines 3e-f, 4f, 3i-j in good to high yields. The Friedel-Crafts type reac tion with arenes also afforded 6-aryl adducts 6a-c. (C) 2001 Elsevier Scien ce Ltd. All rights reserved.
