An unprecedented three-component coupling reaction was developed for the synthesis of 3,4-fused pyrimidin-2-one and pyrimidin-2-thione derivatives from an α-acidic imine compound, a nitrile, and triphosgene or carbon disulfide. This method can be used to easily prepare a variety of pyrimidines from commercially available reagents in a single step. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
开发了一种前所未有的三组分偶联反应,用于从 α-酸性亚胺化合物、腈和三光气或二硫化碳合成 3,4-稠合嘧啶-2-one 和嘧啶-2-硫酮衍生物。该方法可用于在一个步骤中从市售试剂轻松制备各种嘧啶。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
