Auch an aliphatische Aldehyde wird in bisher kaum erreichten Selektivitäten (bis > 99.5:0.5) Et~2~Zn enantioselektiv addiert, wenn als Katalysator das Siebenringtitanat 1 und stöchiometrische Mengen Ti(OCHMe~2~)~4~ zugesetzt werden. Es besteht eine __lineare__ Beziehung zwischen den Enantiomerenrein
