Reactions of 2-Arylthio-and 2-Arylsulfonyl-1-nitro-1-phenylethenes with Amines

2-Arylthio- and 2-arylsulfonyl-1-nitro-1-phenylethenes react with amines to give the corresponding nitroenamines whose configuration (E or Z) depends on the amine structure. Primary amines gives rise to Z-nitroenamines, secondary cyclic amines with 2-aryl

Reaction of 2-Nitroenamines and 2-Nitroalkenyl Sulfides with Ethyl Isocyanoacetate. A Novel Synthesis of 1-Hydroxypyrazoles

We have show that 1-hydroxypyrazoles can be prepared easily and regioselectively from the reaction of nitroenamines with ethyl isocyanoacetate. α,β-Unsaturated aci-nitronates are formed in the reaction and are then hydrolysed to give the products by quenching with acid.
