Regioselective Decarboxylative Cycloaddition Route to Fully Substituted 3-CF3-Pyrazoles from Nitrilimines and Isoxazolidinediones

1,4-Diaryl-5-carboxamido substituted 3-trifluoromethylpyrazoles are obtained with exclusive regioselectivity under transition-metal-free conditions. This decarboxylative [3+2] cycloaddition protocol was enabled by employing trifluoromethyl nitrilimines as 1,3-dipoles, and isoxazolidinediones as CO2-masked alkynyl dipolarophiles. The applicability of this method is further manifested by its compatibility with difluoromethyl, alkyl, aryl, and heteroaryl nitrilimines, as well as the preparation of 4-carboxylic amido analogue of drug Celebrex. (Figure presented.).

SYNTHESIS OF 2,2,2-TRISUBSTITUTED 5-TRIFLUOROMETHYL-Δ4-1,3,4,2-OXADIAZAPHOSPHOLINES AND THEIR POTENTIALITY AS PRECURSORS OF TRIFLUOROACETONITRILE IMINES

N'-Phenyl- and methyltrifluoroacetohydrazides react with phosphorus pentachloride to give the corresponding 2,2,2-trichloro-3-phenyl- and methyl-Δ4-1,3,4,2-oxadiazaphospholines, from which various 2,2,2-trisubstituted derivatives are further synthesized.Heating 3-phenyl-2,2,2-tris(p-tolyloxy) analog with an excess of styrene affords 1,5-diphenyl-3-trifluoromethyl-2-pyrazoline, which indicates that the phospholine behaves as a precursor of trifluoroacetonitrile phenylimine.
