Abstract

Inventia se refera la un procedeu pentru prepararea unor derivati de piperazin-2-ona cu formula generala I: (vezi formula) în care R1 si R2 sînt în mod independent hidrogen sau alchil cu 1 la 4 atomi de carbon, R3 reprezinta un atom de hidrogen, R4 reprezinta un atom de hidrogen, o grupa alcoxicarbonil cu 1 la 6 atomi de carbon sau o grupa -CO-R5 în care R5 reprezinta o grupa alchil cu 1 la 6 atomi de carbon, eventual substituita cu alcoxicarbonil cu 1 la 6 atomi de carbon, nitrobenzoil sau aminobenzoil, cu conditia ca R1, R2 si R4 sa nu foie în mod simultan atomii de hidrogen. Procedeul consta în aceea ca se trateaza un compus cu formula generala II: (vezi formula) în care R este benziloxicarbonil sau are aceeasi semnificatie cu R4, cu un compus cu formula generala III: (vezi formula) în care R1 si R2 au seminificatiile de mai sus, în mediu dimetilformaldehida sau acetona, în prezenta de hidrura de sodiu, metoxid de sodiu, carbonat de sodiu sau hidroxid de sodiu sau potasiu la temperatura cuprinsa între 20 si 55 degree C compusii obtinuti putînd fi transformati, în mod cunoscut, în saruri acceptabile farmaceutice.
