Abstract
N-tert-butyloxycarbonyl-S-benzyl-cysteine, N-fluorenylmethyloxy-carbonyl-alanine-, S-trityl-cysteine-, O-tert-butyl-serine- and O-tert-butyl-tyrosine were converted to the corresponding alcohols via sodium borohydride reduction of their in situ formed methyl esters. Enantiopurity of the products was checked by chiral HPLC method.
