A set of electrophilic 2-(trifluoroacetyl)-1,3-azoles demonstrated excellent activity in the C-oxyalkylation of pyrrole, furan, thiophene, 1,3-thiazole, and 1,2-oxazole derivatives. The reaction conditions and the yields of the corresponding trifluoromethyl-substituted alcohols depend strongly on both the electronic and steric nature of the 1,3-azole unit.
一组电亲性2-(三氟乙酰基)-1,3-唑类化合物在吡咯、呋喃、噻吩、1,3-噻唑和1,2-噁唑衍生物的C-氧烷基化反应中表现出了优异的活性。反应条件和相应三氟甲基取代醇的产率强烈依赖于1,3-唑单元的电子性质和立体性质。
