An efficient and practical strategy was developed to synthesize 1,3,4-triaryl-6-trifluoromethylpyridones from CF-imidoyl sulfoxonium ylides and cyclopropenones in good to excellent yields. This stepwise [3 + 3] annulation reaction was carried out under transition-metal-, additive-, and solvent-free conditions, generating 1 equiv of dimethyl sulfoxide as byproduct and tolerating a series of functional groups.
开发了一种高效实用的策略，以良好至优异的产率从CF-亚胺基硫鎓叶立德和环丙烯酮合成1,3,4-三芳基-6-三氟甲基吡啶酮。这种逐步的[3 + 3]环化反应在无过渡金属、无添加剂和无溶剂的条件下进行，生成1当量的二甲基亚砜作为副产物，并能耐受一系列官能团。
