The present invention relates in general to the field of organic chemistry and in particular to the preparation of alpha-amino boronic esters. These compounds can be used as intermediates in the synthesis of boronic acid and ester compounds such as N- terminal peptidyl boronic acid derivatives, for example N-(pyrazin-2-yl)carbonyl-L-phenylalanine-L-leucine boronic acid, i.e. bortezomib.
