dc.description	Two C2-symmetric bis(sulfonamide) ligands containing fluorene-chiral (1R,2R)-cyclohexane-1,2-diamine were complexed to RhIII(Cp*) and used as catalyst to reduce aromatic ketones. The corresponding chiral secondary alcohols were obtained in 87-100% ee and 85-99% yield, under asymmetric transfer hydrogenation (ATH) conditions using aqueous sodium formate as the hydride source. With acetophenone, 94% ee and 86-97% yield was achieved with substrate/catalyst (S/C) ratio of 10,000.	es_ES

Los correspondientes alcoholes secundarios quirales se obtuvieron en 87-100% de ee y 85-99% de rendimiento, en condiciones de hidrogenación de transferencia asimétrica (ATH) usando formiato de sodio acuoso como fuente de hidruro. Con acetofenona, se obtuvo un 94% de ee y un rendimiento de 86-97% con una relación de sustrato / catalizador (S / C) de 10.000.	es_ES
