Journal ArticleDOI
Sodium bromide catalysed one-pot synthesis of tetrahydrobenzo[b]pyrans via a three-component cyclocondensation under microwave irradiation and solvent free conditions
Ipsita Devi,Pulak J. Bhuyan +1 more
TL;DR: Sodium bromide catalysed three-component cyclocondensation of aryl aldehydes, alkyl nitriles and dimedone proceeds under microwave irradiation in solvent free conditions to give highly functionalised tetrahydrobenzo[b]pyrans in excellent yields as discussed by the authors.
Journal ArticleDOI
Uncatalysed Knoevenagel condensation in aqueous medium at room temperature
Mohit L. Deb,Pulak J. Bhuyan +1 more
TL;DR: In this article, the condensation of various aromatic and heteroaromatic aldehydes with active methylene compounds like malononitrile, e.g., barbituric acids, Meldrum's acid, dimedone and pyrazolone is described.
Journal ArticleDOI
An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature
Mohit L. Deb,Pulak J. Bhuyan +1 more
TL;DR: In this article, a protic solvent at room temperature in the absence of any other catalyst to afford bis(indolyl)-methanes in excellent yields was used for electrophilic substitution reactions of indoles with various aldehydes.
Journal ArticleDOI
A novel three-component one-pot synthesis of pyrano[2,3-d]pyrimidines and pyrido[2,3-d]pyrimidines using microwave heating in the solid state
TL;DR: Microwave-assisted three-component cyclocondensation of barbituric acids, benzaldehyde and alkyl nitriles was shown to yield pyrano[2,3-d]pyrimidines.
Journal ArticleDOI
Synthesis of some complex pyrano[2,3-b]- and pyrido[2,3-b]quinolines from simple acetanilides via intramolecular domino hetero Diels–Alder reactions of 1-oxa-1,3-butadienes in aqueous medium
Biswajita Baruah,Pulak J. Bhuyan +1 more
TL;DR: Some complex pyrano[2,3b]- and pyrido [2, 3b]-quinolines were synthesized from simple acetanilides via intramolecular domino hetero Diels-Alder reactions of 1-oxa-1,3-butadienes using water as solvent as discussed by the authors.
