4-Hydroxy-N′-(4-methoxybenzylidene)benzohydrazide
Autor: Da-Hua Shi
Publikováno v: Acta Crystallographica Section E, Vol 65, Iss 9, Pp o2107-o2107 (2009)
The title compound, C15H14N2O3, was synthesized by the reaction of 4-methoxybenzaldehyde with 4-hydroxybenzohydrazide in methanol. The molecule adopts an E configuration about the C=N bond. The two benzene rings make a dihedral angle of 46.6 (2)°. I

Autor: Wang Youxian, Zhiling Cao, Shu-Ting Ren, Lei Wang, Da-Hua Shi, Yu-Ran Wu, Wei-Wei Liu, Shu-Hao Liu
Publikováno v: Journal of Chemical Research. 44:363-366
Eight glycosyl benzoxazole derivatives are synthesized by nucleophilic addition reactions of glycosyl isothiocyanate with o-aminophenol in tetrahydrofuran. The reaction conditions are optimized, and good yields (86%–94%) were obtained. The structur
