The syntheses of several N-aryl-3-amino-4-nitroisothiazol-5(2H)-imines 12 from 3,3-diamino-2-nitrothioacrylamides 11 are reported (Scheme 3). In polar solvents, a spontaneous isomerization of some of the prepared isothiazol-5(2H)-imines 12 yielded be

A new immunochemical label was synthesized and used as an artificial hapten to obtain a monoclonal antibody that specifically recognizes it. The new cytidine analogues, 5-methyl-4-N-{4-[6-(p-bromobenzoylamido)caproylamido]but-1−yl}-2′-deoxycytidi

Reaction of N-acyl-3,3-diamino-2-nitroacrylthioamides 1 with MeI at room temperature leads to N-acyl-S-methyl-3,3-diamino-2-nitroacrylthioimidates 2 in moderate yields. The latter react with Hg(OAc)2 in DMF yielding 3-(acylamino)-3-amino-2-nitroacryl
