CHIRAL DERIVATIVES OF HYDROXYPHENYLGLYCIN, AND THEIR USE IN THE SYNTHESIS OF PHARMACEUTICAL ACTIVE PRINCIPLES

摘要

The chiral derivatives of hydroxyphenylglycin, with the configuration D, have general formula (I), wherein R is H, hydroxy, chloride, -NH2, -NHW, wherein W is an alkyl C1-C4 or aryl group, -OR', wherein R' is an alkyl C1-C4 group, and Z is H, -CONH2 and -C(CH3)=CHCOOY, wherein Y is methyl or ethyl. One of said compounds, D-(-)-2-(2'-hydroxyphenyl)glycin, may be obtained by enzymatic process from the corresponding hydantoin while the others may be obtained by chemical or enzymatic process. The compounds of formula (I) are useful for the production of drugs, particularly for semisynthetic penicillins, cephalosporins, non steroid and mucolytic antiinflammatory agents.
