USE OF PENTAFLUOROPHENYL ESTERS IN THE SYNTHESIS OF INTERMEDIATE FRAGMENTS OF ACTH

The results are given of the synthesis of the heptapeptide 13-19 of the natural sequence of ACTH using, in a number of stages, the pentafluorophenyl esters of amino acids and peptides in combination with the temporary silyl protection of the carboxy group
