Alum-catalyzed one-pot synthesis of dihydropyrano[3,2-b]chromenediones

A simple, green and efficient solventless procedure for the synthesis of eleven dihydropyrano[3,2-b]chromenediones from the three-component condensation reaction of kojic acid, aromatic aldehydes, and dimedone using a reusable alum as catalyst is describe

Anchoring of nickel (II) kojic acid in functionalized Si-MCM‐41 matrix: a effective nanocatalyst for the catalytic clean synthesis of dihydropyrano[3,2-b]chromenediones

Green solventless preparation of dihydropyrano[3,2-b]chromenediones was developed by a three-component reaction (3-CR) of dimedone, different aldehydes, and kojic acid that catalyzed with nano-silica-MCM‐41‐kojic acid‐Ni as a reusable, efficient, and high

Nano-pistachio hull-O xTiCl4?x: synthesis, characterization and application as an effective and novel nanocatalyst for one-pot synthesis of dihydropyrano[3,2-b]chromenedione derivatives

According to the Food and Agriculture Organization (FAO), Iran is the largest pistachio (Pistacia vera) producer in the world. Nevertheless, pistachio by-products (PBs) contain a high level of phenolic and cellulose compounds, it can be used as a substrat

Acetic Acid-Mediated Synthesis of Kojic Acid Derivatives

Abstract: A green acetic acid-mediated synthesis of kojic acid derivatives through amulticomponent reaction (MCR) has been developed. This new protocol is simpleand efficient; it involves a one-pot reaction of equimolar amounts of kojicacid, aromatic alde

Bcl3 catalyzed, solvent free protocol for the synthesis of dihydropyra-no[3,2-b] chromenediones

Solvent free synthesis of dihydropyrano[3,2-b]chromenediones was formulated via multi-component reactions of kojic acid, dimedone and several substituted aromatic aldehydes catalyzed with BCl3. Reactions progressed efficiently and the correspon

A meglumine catalyst–based synthesis, molecular docking, and antioxidant studies of dihydropyrano[3, 2-b]chromenedione derivatives

A simple method was employed for the synthesis of dihydropyrano[3, 2-b]chromenedione derivatives (4a-o) in high yields by condensation of 5, 5-dimethylcyclohexane-1, 3-dione(1), different aromatic aldehydes (2a-o), and 5-hydroxy-2-(hydroxymethyl)-4H-pyran
