SOLVENT-FREE SYNTHESES OF SALICYLALDIMINES ASSISTED BY MICROWAVE IRRADIATION
摘要:
A microwave-assisted condensation of salicylaldehyde and aryl amines without solvent were efficiently performed to form a series of salicylaldimines in high yields, which were confirmed by IR, H-1 NMR, C-13 NMR and elemental analyses. The microwave-assisted condensation provided a convenient environmental-friendship methodology for syntheses of Schiff-base in organic syntheses.
Synthesis of novel isoxazolyl 1,3,5-benzoxadiazocines has been accomplished by condensation of 3-amino-5-methylisoxazole with salicylaldehydes, followed by reduction, treatment with arylisothiocyanates, and subsequent ring closure in the presence of formaldehyde. The methodology used in this synthesis is the first approach of its kind. J. Heterocyclic Chem., 46, 134 (2009).
Abstract The reaction between primary amine and aldehyde usually leads to a Schiff base. In this work, we present the results of research (NMR, ATR-FTIR, UV–Vis, and X-ray) of products obtained in the reaction of 5-methyl-3-aminoisoxazole (3AMI) or 3-methyl-5-aminoisoxazole (5AMI) with 17 different aldehydes. Based on the results, we prove that this simple and well-known reaction does not always leads
