2-Nitromethylenethiazolidine has been synthesised and found to be a weak enamine. It reacts with acyl isothiocyanates but not with phenyl isothiocyanate. Oxidative cyclization of the acyl isothiocyanate adducts leads to isothiazolo [3,2-b] thiazole derivatives. The 2-benzoylimino compound8 undergoes base catalysed fragmentation to give the nitronitrile9.
