Abstract

Inventia se refera la un procedeu pentru prepararea unor 9-fluor-prednisolone cu formula I: (vezi form. in desc.) în care X reprezinta o grupa alcanoil oxi cu 3....8 atomi de carbon, iar R1 reprezinta o grupa alcanoil cu 1....8 atomi de carbon alcanoil cu 1....8 atomi de carbon sau o grupa benzoil, conform caruia un alcool cu formula generala II: (vezi form. in desc.) este esterificat cu ajutorul unui compus cu formula generala III: (vezi form. in desc.) în care Z reprezinta un atom de fluor sau o grupa R2CO-O, iar R2 este o grupa alchil cu 2....7 atomi de carbon, în prezenta unor acizi, ca de exemplu, acid clorhidric, p-toluensulfonic sau trifluoracetic, sau în prezenta unei baze ca bicarbonat de potasiu colidina, 4-dimetilaminopiridina sau piridina la temperatura camerei.
