Efficient Synthesis of Pyrido[3,2-c[coumarins via Silver Nitrate Catalyzed Cycloisomerization and Application to the First Synthesis of Polyneomarline C

Herein, we report an efficient method for the synthesis of the pyrido[3,2-c[coumarin scaffold, one of the privileged heterocycle-fused coumarin scaffolds, via a AgNO 3-catalyzed cycloisomerization of 4-(propynylamino)coumarins obtained from div

Cu(I)-mediated lactone formation in subcritical water: A benign synthesis of benzopyranones and urolithins A-C

Benzopyranones were successfully synthesized using Cu(I)-mediated C-O bond formation in subcritical water. A number of benzopyranone derivatives including polymethoxy benzopyranones, benzopyranopyridones, chromenoindolones, and furochromenones were synthesized in satisfactory yield. This methodology was further applied to synthesize the intestinal microbial metabolites, urolithins A, B, and C, which were found to exhibit potent antioxidant activity.

Pyran Derivatives, 96. - Benzopyranopyrrole and -pyridine Derivatives

Five- or six-membered ring lactams 1 condense with 2-hydroxybenzoates 2 to yield 2-acyl-4-butane- and -5-pentanelactams 3 which can be converted into the saturated benzopyranopyrrolones and -pyridinones 14 and 23, respectively.The intermediates
