Abstract
Inventia se refera la un procedeu pentru prepararea unor acizi 7-amino-3-metil-substituit-delta cub-cefem-4-carboxilici cu formula generala I: (vezi formula) în care R1 reprezinta un atom de hidrogen sau o grupa p-nitrobenzil, etil sau difenilmetil, R2 reprezinta o grupa triazolil sau tetrazolil eventual substituita cu unl sau doi substituenti alesi dintre un atom de halogen, o grupa alchil cu 1...4 atomi de carbon, tioalchil cu 1...4 atomi de carbon, alcoxi-carbonil cu 1...4 atomi de carbon, cian, amino, acilamino cu 1..4 atomi de carbon, fenil, difenilmetoxicarbonil sau alcoxicarbonilalchul în care grupele alchil cu 1...4 atomi de carbon, grupa triazolil sau tetrazolil fiind legata la grupa exometilen printr-o legatura carbon-azot, constînd din aceea ca un compus cu formula generala II: (vezi formula) în care R1 are semnificatiile de mai sus si Z reprezinta S sau S-O reactioneaza cu un triazol sau tetrazol, eventual substituit cu sunstituientii radicalului R2, într-un solvent organic ales dintre sulfonat, acid trifluoracetic, acetat de etil, nitrometan, acid acetic, cloracetat de etil si acetonitril, în prezenta unui acid sau complex cu carcater acid ales dintre acid sulfuric, metansulfonic, trifluormetansulfonic, fluorsulfonic, trifluorura de bor si trifluorura de bor-eterdietilic, la o temperatura cuprinsa între între temepratura camerei si 60 degree C, grupa amino putînd sa fie eventual protejata în timpul reactiei, dupa care, daca se doreste, compusul cu formula I obtinut poate fi transformat într-o sare, un ester sau un acid liber, prin metode în sine cunoscute.
