Mohamadpour, Farzaneh published the artcileSynthesis of Pyran-Annulated Heterocyclic Systems Catalyzed by Theophylline as a Green and Bio-Based Catalyst, Safety of 2,3-Dimethoxybenzaldehyde, the main research area is tetrahydrobenzopyran preparation green chem; aryl aldehyde malononitrile dimedone tandem theophylline biocatalyst; pyranopyrimidinone preparation green chem; malononitrile aryl aldehyde barbituric acid tandem theophylline biocatalyst; dihydropyranopyrazole preparation green chem; ethyl acetoacetate aldehyde hydrazine hydrate malononitrile tandem theophylline biocatalyst.
A green synthetic route to the convenient preparation of tetrahydrobenzo[b]pyrans I [R1 = Ph, 4-O2NC6H4, 2,3-(H3CO)2C6H3, etc.], pyrano[2,3-d]pyrimidinones II (R2 = Ph, 2,4-Cl2C6H3, 2-O2NC6H4, etc.; R3 = H, Me) and dihydropyrano[2,3-c]pyrazoles III (R4 = Ph, 3-O2NC6H4, 2-OHC6H4, etc.) scaffolds have been developed using theophylline as a green and bio-based catalyst via tandem Knoevenagel-Michael cyclocondensation reaction in aqueous/ethanol media. All reactions are completed in short period of times and the products are obtained in excellent yields. The salient features of this environmentally friendly approach are green and bio-based catalyst, straightforward work-up with no column chromatog. separation, one-pot procedures, economical and clean synthesis, avoidance of toxic organic solvents and high atom-economy.
