Abstract

Dibutyl-2-(trifluoromethyl)cyclopropylboronate 2, available in one step from commercially available reagents, serves as a useful (trifluoromethyl)cyclopropylating reagent by participating in a palladium-catalyzed Suzuki coupling. The use of boronate ester 2 in medicinal chemistry was exemplified by preparation of TRPV1 receptor antagonists.

Graphical abstract

Compound 2 can act as a (trifluoromethyl)cyclopropyl donor by participation in a Suzuki reaction.
