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.
一种简便的方法,利用三氟乙酸酐对咪唑、1,3-噻唑和1,3-噁唑进行三氟乙酰化,得到了一系列含三氟甲基的杂环酮。与常见的酮不同,这些化合物形成稳定的醇合物,并与末端烯烃发生非催化性Ene反应,生成相应的烯丙醇。
