, p. 948 - 956 (2008/09/21)

A facile method of trifluoroacylation of imidazoles, 1,3-thiazoles, and 1,3-oxazoles with trifluoroacetic anhydride resulted in a set of heterocyclic trifluoromethyl-containing ketones. Unlike common ketones, these compounds form stable hydrates and enter into noncatalytic ene reactions with terminal olefins affording the corresponding allyl alcohols. Georg Thieme Verlag Stuttgart.
