    摘要: Organoboronic acids, for example Cbz-(R)-Phe-(S)-Pro-(R)-Mpg-B(OH)2, are made by hydrolysing their diethanolamine adducts under conditions which avoid substantial C—B bond breakage. The product acids are substantially free of degradation product derived from cleavage of the C—B bond thereof. The acids are used to make base addition salts thereof. The salts are formulated into anti-thrombotic pharmaceutical formulations.
