Action of Grignard Reagents. XIV.1 Action of Organomagnesium Compounds on 1-Phenyl-3-methyl-4-arylidene-5-pyrazolones. Their Behavior toward Aromatic Secondary Amines and Aromatic Thiols
reaction of 4-arylidene-3H-pyrazol-3-one 1 with secondary and tertiary carbanionsderivedfrom a methylene and methine group bearing both a leaving group and electron-withdrawing group, e.g. methyl chloroacetate, ethyl chloroacetate, isopropyl chloroacetate, tert-butyl chloroacetate, chloroacetonitrile, 2-chloro-N,N-diethylacetamide, methyl 2-chloropropionate and 2-chloropropionitrile, in the presence of
Chemical reactivity and application of 4-alkylidene-3H-pyrazol-3ones are described. Furthermore, twelve of the newly synthesized O-substituted pyrazoles were evaluated for their antifungal activity in vitro against Candida albicans and Saccharomyces cerevisiae.
