Synthesis of aryl esters of protected amino acids from aryl sulfonates

Article abstract of DOI:10.1016/S0040-4039(99)01178-8

Aryl esters of Boc- and Fmoc-protected amino acids derived from electron-deficient phenols have been prepared in good yields from aryl 4- nitrobenzenesulfonates in the presence of 1-hydroxy-benzotriazole as catalyst.
