A facile and efficient synthesis of tetrahydrobenzo[b]pyrans and dihydropyrano[4,3-b]pyrans derivatives using phosphate fertilizers MAP, DAP, and TSP as heterogeneous catalysts

A simple and efficient one-pot synthesis of tetrahydrobenzo[b]pyrans and dihydropyrano[4,3-b]pyrans derivatives was described. These reactions were realized through a three-component condensation of aromatic aldehyde, malononitrile, and 5,5-dimethyl-1,3-c

Ceria-Vanadia/Silica-Catalyzed Cascade for C-C and C-O Bond Activation: Green One-Pot Synthesis of 2-Amino-3-cyano-4H-pyrans

We designed a ceria-vanadia/silica (Ce-V/SiO2) heterogeneous catalyst and used it for the green and efficient synthesis of 2-amino-3-cyano-4H-pyran derivatives. The green reaction was a multicomponent one-pot condensation of 5,5-dimethylcyclohe

Caffeine catalyzed synthesis of tetrahydrobenzo[b]pyran derivatives: Synthesis and insight into kinetics and mechanism

Aim and objective: Tetrahydrobenzo[b]pyran derivatives are considered as a special class in drug research because of their various biological and pharmacological benefiting usages. In the current work, we developed new synthetic methods for the preperatio
