Abstract
Una síntesis simple, de alto rendimiento, de alfa-cloro cetonas, de la fórmula (I) donde Y es cloro o flúor y A es un nucleófilo de carbono quecomprende: (a) hacer reaccionar un reactivo organometálico de fórmula (A-M) en donde M es Li o Mg, con un compuesto de fórmula (III), en donde X es -NR(OR1);R y R1 son cada uno, independientemente, alquil C1-3 lineal o ramificado, cicloalquil C3-6 u opcionalmente substituido con alcoxi C1-3, fenil, fenilsubstituido, en donde el substituto en el fenil se selecciona de F, Cl, Br, metiltio, -OH, metoxi, aminotio y alquil C1-3;en un solvente orgánico aprótico,y (b) hacer reaccionar sin purificación adicional al producto del paso (a) con una solución acuosa de ácido G, para dar una fase con solvente orgánicoaprótico que comprende un compuesto de fórmula (I) y una fase de solvente acuoso que comprende a un compuesto de fórmula (III). En la fórmula (I), Y escloro o fluor y A es un nucleófilo de carbono, que abarca la acilación dereactivos de Grignard y de organolitio con N-metoxi-N-metilcloracetamida. Laeficiencia del procedimiento se mejora ulteriormente reciclando la N,O- dimetilhidroxilamina.
