Abstract

Den foreliggende oppfinnelsen tilveiebringer nye fremgangsmåter for den asymmetriske syntesen av (S)-6-klor-4-cyklopropyletynyl-4-trifluormetyl-l,4-dihydro-2H-3,1- benzoksazin-2-on med formel (Vl-i) som er anvendelig som en human immunsviktvirus (HIV) revers transkriptase inhibitor. I en utførelsesform tilveiebringer foreliggende oppfinnelse en fremgangsmåte for fremstilling av en aminoalkoholforbindelse med formel (V-i) som innbefatter tilsetting av en toluenløsning av 2,3-diklor-5,6-dicyano-l,4- benzokinon til en toluenløsning av en forbindelse med formel (IH-i), via en forbindelse med formel (IV-i).
