Abstract
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.
Key words
fluorine compounds - acylations - ketones - nitrogen-containing heterocycles - stable hydrates
