Process for the synthesis of optically active aminoacids

New process for the synthesis of optically active aminoacids of formula STR1 by treating compounds of formula STR2 which an optically active alcohol of formula To obtain a pair of diastereoiosmer esters of formula STR3 which is resolved in basic medium into the single diastereoisomer esters of formula STR4 from which the desired optically active aminoacid of formula (I) is obtained by treatment in acid medium.
