Nano silica sulfuric acid catalyzed synthesis of 2-substituted aryl (indolyl) kojic acid derivatives
Nano silica sulfuric acid as a solid acid, was described to be an effective catalyst for one-pot three-component reaction of kojic acid, aryl aldehydes and indoles for the preparation of 2-substituted aryl (indolyl) kojic acid derivatives. The catalyst was prepared by combination of chlorosulfonic acid to nano silica gel. The size of nanoparticles were observed with SEM.All prepared compounds w...
In the title compound, C(13)H(11)NO(4)S, the dihedral angle between the planes of the benzene ring and the carboxyl group is 13.7 (1)°. The mol-ecular structure contains intra-molecular N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, while the crystal packing is stabilized by C-H⋯O and O-H⋯O hydrogen bonds and C-H⋯π inter-actions. The O-H⋯O hydrogen bonds form a cyclic dimer, with graph-set mot...
