Preparation of amino acid derivatives
摘要:
A hydroxy-carboxylate ester is converted to an amino-acid-amide by replacement of the --OH group with --N.sub.3, via, e.g., CH.sub.3 SO.sub.2 Cl and NaN.sub.3 ; reacting with amine to convert the ester to amide; and hydrogenating --N.sub.3 to --NH.sub.2. The present process alleviates the conventional use of blocking-deblocking procedures.
