Cerium(III) chloride-catalyzed one-pot synthesis of tetrahydrobenzo[b] pyrans

Efficient one-pot synthesis of 4H-benzo[b]pyrans via a three-component cyclocondensation of aryl aldehydes, malononitrile, and dimedone has been reported using CeCl3·7H3O as catalyst. Copyright Taylor & Francis Group, LLC.

Solvent Selective Polyacrylonitrile Fiber as a Recyclable Catalyst for the Knoevenagel-Michael Reaction in Water

Heterogeneous catalysis is an important branch of sustainable chemistry. In this work, a series of polyacrylonitrile fiber (PANF) fiber catalysts (PANF-E, PANF-EDs, and PANF-D) with different catalytic micro-environments are developed and characterized by

One-pot cascade synthesis of benzopyrans and dihydropyrano[c]chromenes catalyzed by lipase TLIM

Lipase TLIM was reported to be an efficient, commercially available and reusable catalyst for the Knoevenagel-Michael cascade reactions of aldehydes, malononitrile/ethyl cyanoacetate and 4-hydroxycoumarin/1, 3-cyclohexanedione/dimedone in aqueous DMSO. Th

Efficient and green synthesis of 4H-pyran derivatives under ultrasound irradiation in the presence of K2CO3 supported on acidic montmorillonite

Acid-treated montmorillonite coating with K2CO3 is used as a catalyst for an efficient, rapid, one-pot synthesis of 4H-pyran derivatives in good yield under ultrasonic irradiation. The catalyst is environmentally benign, easy handlin

Meglumine: A novel and efficient catalyst for one-pot, three-component combinatorial synthesis of functionalized 2-amino-4 H-pyrans

An efficient one-pot synthesis of functionalized 2-amino-4H-pyrans by a meglumine-catalyzed three-component reaction has been developed. A broad range of substrates including aromatic and heteroaromatic aldehydes, isatin derivatives, and acenaphthenequino
