Preparation of Homologous Pyrazolonedicarboxylates
摘要:
Homologous disodium pyrazolonedicarboxylates (8, 16f and 16g) as possible protectors of cis-DDP induced nephrotoxicity, have been prepared by the reaction of hydrazine with di-t-butyl ethyl beta-keto triesters (5b, 13b and 13c) and subsequent hydrolysis of formed di-t-butyl pyrazolonedicarboxylates (6b, 14b and 14c).
