Abstract

NEW MATERIAL:A penicillin derivative shown by the formula I (R1 is H or OH; R2WR5 are H, OH, alkyl, etc. with the exception that all of R2WR5 are H) and its nontoxic salt.
EXAMPLE: D(-)-α-(7-acetoxychromone-3-carbonylamino)benzylpericillin.
USE: An antibacterial agent. Effective against gram-positive and gram-negative and gram-negative bacteria, especially pseudomonas aeruginosa and low toxic.
PROCESS: A compound shwon by the formula II, its salt, or its hydrate, is reacted with a compound shown by the formula III or its reactive derivative to give a compound shown by the formula I or its salt. The reaction is carried out in an inert solvent, e.g., acetone, etc., and, if necessary, in the presence of a dehydrating and condensation agent, a base or a silylating agent.
