A domino desulfitative coupling/acylation/hydration process to synthesize C-2-(2-oxo-2-phenylethylidene)- and N-3-carbonyl-substituted pyrimidines by unprecedented CC and CN cross-coupling reactions is described. This methodology couples 3,4-dihydropyrimidine-2-thiones and alkynes under modified Liebeskind–Srogl conditions using palladium acetate and copper(I) carboxylate. Remarkably the copper(I)
描述了通过空前的CC和CN交叉偶联反应合成C-2-(2-氧代-2-苯基亚乙基)-和N-3-羰基取代的嘧啶的多米诺脱硫偶联/酰化/水合方法。这种方法在改良的Liebeskind-Srogl条件下使用乙酸钯和羧酸铜(I)偶联3,4-二氢嘧啶-2-硫酮和炔烃。值得注意的是,羧酸铜(I)同时在反应中充当脱硫剂和酰化剂。
