Syntheses of 4-amino-3,5-dinitropyrazoles were achieved from four different starting materials (14JHC1621). 1,3-Di-substituted pyrazoles 32 were smoothly synthesized from the copper-catalyzed cascade reactions of oxime acetates 31, aniline, and paraformaldehyde (14CC14793). Nitroallylic acetates 33 and N-tosylhydrazine underwent cascade regioselective reaction to give ethyl pyrazole-5-carboxylates 34 (14T795). 

A different approximation was reported by Tang, Li, and co-workers [56] by using Seebach s nitroallylic acetate reagent 85, cyclohexanones, and proline-thiourea derivative XXVI as a catalyst. Nitroallylic acetate reacts with cyclohexanones via a double Michael addition, affording the final fused bicyclic ketones 86 in excellent yields and stereoselectivities (Scheme 10.24). 

Substituted naphtho[lr]furans and benzo[fc]furans were easily accessible by treatment of naphthols/substituted phenols with nitroallylic acetates through a substitution-elimination process promoted by cesium carbonate (13CEJ4344). Aminobenzo[l)]furan could be obtained by a one-pot con-densation-cyclization sequence from ethyl glycolate with chloropyridine (13BMCL2781). An intramolecular cyclization of 2-(gem-dibromovinyl) phenols(thiophenols) produced 2-bromobenzo[lr]furans(thiophenes) in the presence of Cu (13OBC4095).
