  Diversity-Oriented Synthesis of 1-Substituted 4-Aryl-6-oxo-1,6-dihydropyridine-3-carboxamides.

  摘要：

  A simple five-step diversity-oriented synthesis of 1-substituted 4-aryl-6-oxo-1,6-dihydropyridine-3-carboxamides was developed. Treatment of dimethyl 2-((dimethylamino)methylidene)-3-oxopentanedioate with twenty primary amines gave 1-substituted methyl 4-hydroxy-6-oxo-1,6-dihydropyridine-3-carboxylates. Transformation into the corresponding 4-tosyloxy and 4-chloro derivatives, followed by Suzuki-Miyaura arylations gave a series of eleven N-substituted methyl 4-aryl-6-oxo-1,6-dihydropyridine-3-carboxylates. Combinatorial screening was employed to establish suitable reaction conditions for Suzuki-Miyaura arylation of N-alkylpyridones. Hydrolysis of the esters followed by parallel solution-phase amidation of the corresponding carboxylic acids with primary and secondary amines furnished a library of seventeen final products.

  A general and catalytic α-arylation of cyclic 1,3-dicarbonyls have been developed, providing expedient access toward a wide range of high-value 2-aryl (hetero)cyclic 1,3-dicarbonyls. The key to success is through a cyclic iodonium ylide strategy. Our approach is base-free and exhibits broad substrate scope (>100 examples). Importantly, our approach allows late-stage modification and significantly simplifying
