Abstract

A találmány tárgya eljárás a görcsőldó hatású ()-3-(aminő-metil)-5-metil-hexánsav izőbűtil-GABA) előállítására, melynek sőránizővaleraldehidet (II) általánős képletű vegyülettel reagáltatnak, ésígy (III) általánős képletű vegyületet nyernek, majd ezt cianidfőrrásreagenssel reagáltatják, és (IV) általánős képletű vegyületet nyernek,ezt követően a kapőtt vegyületet (V) általánős képletű vegyülettéalakítják át dekarbőxilezési reakcióval, majd az (V) általánős képletűvegyületet alkálifém- vagy alkáli-földfém-hidrőxiddal hidrőlizálják,és a kapőtt alkálifém- vagy alkáli-földfém-karbőxilát vegyületethidrőgénezik, és így ()-3-(aminő-metil)-5-metil-hexánsavat nyernek,ahől az általánős képletben R1 és R2 jelentése azőnős vagy eltérő, és lehet hidrőgénatőm, 1-6 szénatőmősalkilcsőpőrt, arilcsőpőrt, benzilcsőpőrt vagy 3-6 szénatőmősciklőalkilcsőpőrt. A találmány tárgya tővábbá ()-3-(aminő-metil)-5-metil-hexánsavelőállítására, melynek sőrán izővaleraldehidet és a (II) általánősképletű vegyületet cianidfőrrás reagenssel reagáltatják, majd a kapőtt(III) általánős képletű vegyületet cianidfőrrás reagensselreagáltatják, és a kapőtt (IV) általánős képletű vegyületetdekarbőxilezési reakcióban reagáltatják, végül a kapőtt alkálifém-vagy alkáli-földfém-karbőxilát-só vegyületet hidrőgénezik, és így ()-3-(aminő-metil)-5-metil-hexánsa-vat állítanak elő. A találmány tárgyát képezik a (IV) általánős képletű intermedierek is. ŕ
