We have now succeeded in synthesizing the N-protected triflates of (S)- and (R)-serine methyl ester as well as the N-protected triflates 1 of all diastereomeric threonine methyl esters in very good yields and with complete retention of configuration.eninfo:eu-repo/semantics/openAccessElektrophile Substitution , Alkylierung540article2014-10-16
