The first synthesis of polysubstituted quinoline derivatives from aromatic or aliphatic alcohols with RuCl2(dmso)4 as catalyst under solvent-free conditions is described. The reaction involves the in situ oxidation of alcohols to the corresponding carbonyl compounds through a hydrogen-transfer, followed by a Friedlander annulation process. The whole process is a mild, efficient, selective, and high-yielding
描述了在无溶剂条件下使用 RuCl2(dmso)4 作为催化剂从芳香族或脂肪族醇合成多取代喹啉衍生物的首次合成。该反应包括通过氢转移将醇原位氧化为相应的羰基化合物,然后是 Friedlander 环化过程。整个过程是温和、高效、选择性和高产的一步程序。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
