convergent method for the synthesis of allylicalcohols that involves a reductive coupling of terminal alkynes with α-chloro boronic esters. The new method affords allylicalcohols with excellent regioselectivity (anti-Markovnikov) and an E/Z ratio greater than 200:1. The reaction can be performed in the presence of a wide range of functional groups and has a substrate scope that complements the stoichiometric

Organoboronic acids, for example Cbz-(R)-Phe-(S)-Pro-(R)-Mpg-B(OH)

, 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.
