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

Electrochemical C?O Bond Formation: Facile Access to Aromatic Lactones

An efficient and robust methodology based on electrochemical techniques for the direct synthesis of aromatic lactones through dehydrogenative C?O cyclization is described. This new and useful electrochemical reaction can tolerate a variety of functional groups, and is scalable to 100 g under mild conditions. Remarkably, heterocycle-containing substrates can be employed, thus expanding the scope of radical C?O cyclization reactions.

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.

Novel and efficient one-step parallel synthesis of dibenzopyranones via suzuki-miyaura cross coupling

Microwave-promoted novel and efficient one-step parallel synthesis of dibenzopyranones and heterocyclic analogues from bromo arylcarboxylates and o-hydroxyarylboronic acids via Suzuki-Miyaura cross coupling reaction is described. Spontaneous lactonization

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
