Abstract

NEW MATERIAL: A penicillanic acid derivative of formula I (R1=phenyl, heterocyclic, pyridylthio; R2=H, alkali metal, ammouium, organic base cation, carboxyl protecting group), its optically active isomer, or its salt.
EXAMPLE: Sodium 6-[3'-hydroxy-2'-(1H-tetrazol-1-yl)propionamide] penicillanate.
USE: Anti-microbial agents, effective against gram negative (positive) bacteria.
PROCESS: 6-Aminopenicillanic acid of formula II or its derivative is made to react with 3-hydroxy-2-substituted propionic acid derivative of formula III (R3=H, alcohol protecting group) or its reactive derivative. Then, when R3 is an alcohol protecting group, the protecting group is removed, and when R2 is a carboxyl protecting group, the protecting group is removed if necessary. And if desired, the mixture is then subjected to the optical resolution and/or converted to the salt to give the compound of formula I, its stereoisomer and its salt.
