Coumarin to Isocoumarin: One-Pot Synthesis of 3-Substituted Isocoumarins from 4-Hydroxycoumarins and Benzyne Precursors
TL;DR: A novel transition-metal-free direct synthesis of 3-substituted isocoumarins from 4-hydroxycoumarin and a benzyne precursor is developed, which affords moderate to good yields and is tolerant of a variety of functional groups including halide.
Journal ArticleDOI
Ruthenium half-sandwich complexes with tautomerized pyrazolyl-pyridazine ligands: Synthesis, spectroscopic and molecular structural studies
TL;DR: In this paper, the pyrazolyl-pyridazine ligands were characterized by IR, NMR, mass spectrometry and UV-vis spectroscopy using single crystal X-ray diffraction studies.
Journal ArticleDOI
Efficient organocatalyzed solvent-free selective synthesis of conjugated enones
Papori Goswami,Babulal Das +1 more
TL;DR: In this paper, a series of conjugated dienones and enones were synthesized by a reaction of both simple aldehydes and simple 1,3-dicarbonyl compounds under solvent-free conditions at room temperature.
Journal ArticleDOI
Three-Component Coupling Reactions of Aryne, DMSO, and Activated Alkyne: Stereoselective Synthesis of 2-[(o-Methylthio)aryloxy]-Substituted Dialkyl Maleates
Hemanta Hazarika,Hemanta Hazarika,Kashmiri Neog,Kashmiri Neog,Abhilash Sharma,Abhilash Sharma,Babulal Das,Pranjal Gogoi,Pranjal Gogoi +8 more
TL;DR: A transition-metal-free coupling reaction of aryne, DMSO, and activated alkyne for the synthesis of 2-[( o-methylthio)aryloxy]-substituted dialkyl maleates is reported, which allows preparation of trisubst ituted vinyl ethers with excellent stereospecificity.
Journal ArticleDOI
Water Bridged Assembly and Dimer Formation in Co-Crystals of Caffeine or Theophylline with Polycarboxylic Acids
Babulal Das,Jubaraj B. Baruah +1 more
TL;DR: Caffeine (caf) formed co-crystals with dipicolinic acid (dpa), 3,5-pyrazole dicarboxylic acid (pzca), and trimellitic acid (trimel) with the first two acids as discussed by the authors.
