Autor: D. W. Rustidge, H. R. J. Waddington, M. J. Mardle, J. H. C. Nayler

Publikováno v: J. Chem. Soc. C. :237-242

A number of esters of α-(acylaminosuccinimido)-carboxylic acids were prepared from diesters of N-acyl-α-aspartyl- or N-acyl-β-aspartyl-α-amino-acids; cyclisation occurred either spontaneously or on heating with triethylamine in ethanol. α-(Acyla

Publikováno v: J. Chem. Soc. C. :1920-1922

α-Amino-p-hydroxyphenylacetic acid was resolved and the isomeric amino-acids were coupled with 6-aminopenicillanic acid by two methods to give both epimers of α-amino-p-hydroxybenzylpenicillin. The epimer derived from (–)-D-α-amino-p-hydroxyphen
