On A Safe and Practical Method for The Preparation of β-Keto Phosphonates1
摘要:
Acylations of the magnesium enolate derivatives of trimethyl and triethylphosphonoacetates, using a magnesium chloride-triethylamine system, lead to 2-acylphosphonoacetates which are decarbalkoxylated to give beta-keto phosphonates.

Sulfonamide or phosphonic acid analogs of oxolinic acid (I) and nalidixic acid (II), in which the carboxyl groups of I and II were replaced by sulfamoyl and phosphono groups, were synthesized conveniently by the modification of the Camps'es quinoline synthesis. They were evaluated for antimicrobial activity but no significant activity was noted.
