Abstract
The thiazines (4)-(13) were prepared in high yields from corresponding nitriles or thiocyanates and 4-mercapto-2-methylbutan-2-ol (2) in met hanesulfonic acid. The use of thiocyanates for preparing 2-sulfur-subs tituted thiazines is reported herein apparently for the first time. Th iazines (9) and (10) were observed to exhibit imine-enamine tautomeriz ation by H-1 n.m.r. spectroscopy.
