AbstractA series of (trifluoromethyl)cyclopropanes (TFCPs) tolerating a broad range of functional groups, known as tert-butyl bioisosteres, have been obtained from the cyclization reaction between nitromethane­ and 5-[β-(trifluoromethyl)styryl]isoxazoles in 70–94% yields and 75:25 to 90:10 dr. This method offers practical access to this cyclopropyl moiety of pharmacological interest, employing an inorganic base under phase-transfer conditions.

Tert-butyl esters 3 and 3-cyanopyrrolidines 6 are prepared by phase-transfer-catalysed reactions of symmetrical 4,4′-disubstituted N-(benzylidene)benzylamines with tert-butyl cinnamate and α-phenylcinnamonitrile, respectively; similar reactions of mono-substitited N-(benzylidene)benzylamines afforded mixtures of compounds 3, respectively 6, and their regioisomers 3(A) and 6(A).
