✦ Synopsis

A facile and inexpensive method for the synthesis of 2-substituted benzothiazoles has been developed by Na 2 S 2 O 4 -mediated cyclocondensations of 2,2'-disulfanediyldianilines with aldehydes. In the presence of Na 2 S 2 O 4 and 4 Å molecular sieves, a variety of 2-substituted benzothiazoles were obtained from the reaction of 2,2'-disulfanediyldianilines with aldehydes in moderate to high yields.

Keywords Na 2 S 2 O 4 , cyclocondensation, 2,2'-disulfanediyldianiline, aldehyde, benzothiazole

The reactions of formaldehyde and acetaldehyde with active methylene compounds, followed by reaction with cyanoacetic acid hydrazide 2, afforded N-aminopyridine-2-one derivatives 5a-f. In contrast, the reactions of cyanoacetic acid hydrazide 2 with aliphatic aldehydes and cyanothioacetamide afforded
