Description
Invenția se referă la un procedeu pentru prepararea unor derivați ai perhidroazacicloalca- (1,2-a) -imidazol cu formula generală I:
în care Rt este hidrogen, alchil cu 1 la 4 atomi de carbon, CHR^-CONHR, sau CHR€COOR7 în care R^ și R7 sunt fiecare hidrogen sau alchil cu 1 la 4 atomi de carbon, R2 este hidrogen, alchil cu 1 la 5 atomi de carbon sau un rest R2, dintr-un aminoacid R2CH(NH2)COOH, R3 este hidrogen, alchil cu 1 la 4 atomi de carbon, CONH2 sau CO2Rg, în care R, este hidrogen sau alchil cu 1 la 4 atomi de carbon și n este 2, 3 sau 4.
Scopul invenției este extinderea gamei agenților reootropici.
Probletpa pe care o rezolvă invenția constă în asocierea materiilor prime cu condițiile de reacție pentru obținerea acestor compuși.
Procedeul, conform invenției, constă în aceea că ciclizează un compus cu formula II:
în care R, până la R3 și n sunt așa cum s-au descris pentru formula I, R4 este hidrogen și Rs este hidrogen, ciclizarea se efectuează în prezența hexametildisiloxanului și trimetilclorsilanului la reflux în acetonitril sau toluen sau în prezența unui solvent aprotic dipolar: tetrahidrofuran, acetonitril, dimetilformainidă sau dimetilsulfoxid.
Se dă, în continuare, un exemplu de realizare a invenției.
A. Acid 2-carboxi-4-oxo-2-imidazolidin propanoic
O soluție de acid 2-oxoglutamic 10 g, (0,068 mol), clorhidrat de glicinamidă 8,3 g (0,075 moli), și 8,2 g (0,205 moli) hidroxid de sodiu în 120 ml apă, a fost refluxată timp de 4 h. După răcire, soluția a fost ajustată la un pH de 2,5, iar precipitatul rezultat a fost colectat și uscat sub vid la 60°C, pentru a da 5,9 g de compus din titlu (43%), m.p. 202-205’C.NMR (DMSO-cy·. deltaH = 8,5 (s, 1H. CONH); 7,00-4,00 (b.c., 3H, NH, COOH); 3,22 și 3,18 (ABq, J = 16 Hz, 2H, NHCHjCO); 2,40-1,75 (c.a., 4H,' CHjCHjCOOH). MS (E.I. 70 eV, 1,5 mA), m/z = 140 (M-H2O-COOH)\ 84 (C3H«N2O)*.
B. 2,5-dioxohexahidro-lh-pirolo[ 1,2-aJ-imidazol-7a-carboxiliacid
Un amestec de acid 2-carboxi-4-oxo-2-imidazolidinpropanoic 2 g (9,89 moli), 20 ml hexametildisilazan și trimetilclorosilan 10 ml, în 50 ml acetonitril deshidratat a fost refluxat sub azot, timp de 4 h. După răcire, precipitatul a fost filtrat, iar filtratul a fost evaporat sub vacuum.' Reziduul a fost dizolvat în metanol 20 ml, conținând câteva picături de acid clorhidric concentrat și amestecat pentru 10 min. Materia insolubilă a fost filtrată și filtratul a fost evaporat la uscat. Reziduul a fost triturat cu acetonnitril și cristalizat cu 250 ml tetrahidrofuran pentru a da 0,9 g de compus din titlul (50%), m.p. 207°C(cu descompunere). NMR (DMSO-dJ: deltaH = 9,20 (b.s., 1H, NH .·; 3,82 și 3,46 (ABq, J = 16,8 Hz, 2H, NCIțCO), 2,90-1,80 (c.a., 4H, CH^-CHJ. MS (E.I., 70 eV, 1,5 mA, m/z = 184 (M+), 139 (M-C00H)+, 83 (C3H3N2O)+.
Invenția prezintă avantaje prin aceea că se obțin compuși care pot fi utilizați în terapia ca agenți nootropici.
