A robust, chemoselective direct condensation/cyclization of thioureas and amino alcohols is described. Employing a bench-stable Vilsmeier reagent, methoxymethylene- N , N -dimethyliminium methyl sulfate, the selective in situ activation of alcohols is achieved with high efficiency and broad functional-group tolerance. The reversible interaction of the Vilsmeier reagent with substrate was key to the
描述了硫脲和氨基醇的稳健、化学选择性直接缩合/环化。采用实验室稳定的 Vilsmeier 试剂甲氧基亚甲基-N, N-二甲基亚胺甲基硫酸盐,实现了醇的选择性原位活化,具有高效率和广泛的官能团耐受性。Vilsmeier 试剂与底物的可逆相互作用是这种激活策略成功的关键。
