Sodium hydride-induced cyclization of 1-[(isocyanomethyl)sulfonyl]-4-methylbenzene or ethyl isocyanoacetate with various xanthate esters gave 5-alkoxy-4-tosylthiazoles or ethyl 5-alkoxythiazol-4-ylcarboxylates, respectively, in good to excellent yiel...
In the present study, we report the synthesis of series of novel substituted pyrazoles via 1,3-dipolar cycloaddition reaction. Nitrile imines generated by the catalytic dehydrogenation of hydrazones by chloramine-T, were trapped in situ by 4-(furan-2...
