Abstract:
Ethyl α-substituted cyanoacetates were used to prepare hydrazides, azides, urethanes, and dl-α-amino-β-phenylbutyricacid, dl-α-amino-δ-o-bromophenoxyvaleric acid, and dl-α-amino-δ-o, p-dichlorophenoxyvaleric acid. Ethyl mono- and disubstituted cyanoacetates with hydrazine gave hydrazides which were transformed by treatment with sodium hydroxide into 4-α-phenylethyl-, 4-m-ethylphenoxyethyl-, 4-o-bromophenoxypropyl-, 4-o,p-dichlorophenoxypropyl-, 4,4-m-ethylphenoxy-ethyl-, and 4,4-m-methylphenoxypropyl-3-amino-5-pyrazolones. The ultraviolet absorption spectra of the pyrazolones were determined in neutral, acid, and alkaline solutions and their structures established.
