Heterocyclic Derivatives of 4-Amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one
摘要:
A convenient and scalable preparative method for the synthesis of azomethines from 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one and substituted benzaldehydes, as well as 1,2-oxazole and 1,2-thiazolecarbaldehyde was developed.
