Abstract (en)

[origin: WO8808835A1] Asymmetric hydroformylations of chiral olefins can be achieved by contacting, under hydroformylation conditions, an olefin containing a prochiral center with hydrogen and carbon monoxide in the presence of a catalyst comprising a complex of platinum II and N-(t-butoxycarbonyl)-(2S, 4S)-4-(diphenylphosphino)-2-[(diphenylphosphino)methyl] pyrrolidine and stannous chloride, and removing the resulting chiral aldehyde as it is formed. A preferred method of removing the resulting chiral aldehyde is through the use of a trapping agent such as triethyl orthoformate, trimethyl orthoformate, triethyl orthoacetate, trimethyl orthoacetate, acetone diethyl ketal and acetone dimethyl acetal used in the presence of a solid catalyst support such as cross-linked polystyrene.
