1,4-Disubstituted bis-chromenyl triazole hybrids 5a-m have been synthesized in a three-step reaction sequence from 4-(bromomethyl)-2H-chromen-2-ones 3a-m. The intermediate azides 4a-m underwent a regioselective 1,3-dipolar cycloaddition with a 2H-chromen-2-one linked acetylenic dipolarophile in the presence of Cu (II)/ascorbate/water/n-butanol reaction(More)
In the title compound, C(15)H(19)NO(5), an intra-molecular O-H⋯O hydrogen bond links the hy-droxy-ethyl side chains, forming a seven-membered ring. In the crystal, mol-ecules are linked into chains via O-H⋯O hydrogen bonds along the b axis. Further, mol-ecules are linked by weak inter-molecular C-H⋯O and π-π stacking inter-actions [centroid-centroid(More)
A series of mono and bis-triazole coumarin hybrids 6a-u and 9a-f respectively have been synthesized using 4-(azidomethyl)-2H-chromen-2-ones 5a-i and aryl propargyl ethers 2a-c/8 employing Click chemistry modified protocol for Azide-Alkyne cycloadditions(CuAAC). Anti-tubercular screening showed moderate activity for mono aryloxy compounds 6a-u with MIC(More)
