Abstract

PROCEDURE FOR OBTAINING A PEPTIDE OF FORMULA (I), IN WHICH R1 IS HYDROGEN OR ACID; R6 IS HYDROGEN OR AN AMINO PROTECTION GROUP; R2, R3, R4 AND R5 MAY BE SEVERAL TYPES OF RADICALS; "M" VALUE FROM 1 TO 3, AND "N" VALUE FROM 0 TO 2. CONSISTS OF THE REACTION OF A COMPOUND OF FORMULA (II), OR ITS SALTS, IN WHICH R2, "M" AND "N" HAVE THE SAME MEANING AS IN FORMULA (I); R7 IS A RADICAL ACIL AND R8 IS A PROTECTED HYDROXY GROUP, WITH A COMPOUND OF FORMULA (III), OR ITS SALTS, IN WHICH R3 AND R5 ARE THE SAME AS IN FORMULA (I); AND R9 IS AN AMINO PROTECTIVE GROUP, TO OBTAIN THE COMPOUND OF FORMULA (IV). THE REACTION IS CARRIED OUT BY ACTIVATING THE CARBOXI GROUP OF THE FORMULA COMPOUND (II) AND REACTING IT, WITH THE FORMULA COMPOUND (III), IN AN INERT SOLVENT AT A TEMPERATURE BETWEEN 0ºC AND THE ENVIRONMENT. THE COMPOUND OF FORMULA (IV) CAN BE TRANSFORMED, OPTIONALLY, SUBSTITUTING THE REMAINS WITH CONVENTIONAL METHODS. *FORMULA* (Machine-translation by Google Translate, not legally binding)
