Asymmetric hydroformylation of conjugated dienes catalyzed by chiral phosphine-phosphite-Rh(I) complex

Asymmetric hydroformylation of conjugated dienes has been investigated using (R,S)-BINAPHOS-Rh(I) complex as a catalyst [(R,S)-BINAPHOS = (R)-2-(diphenylphosphino)-1,1'-binaphthalen-2'-yl (S)-1,1'-binaphthalene-2,2'-diyl phosphite]. Optically active β,γ-unsaturated aldehydes were obtained in high regio- (78-94%) and enantioselectivities (80-97% ee) from 1-vinylcyclohexene, 4-methyl-1,3-pentadiene, and (E)-1-phenyl-1,3-butadiene. On the other hand, hydroformylation of 1,3-butadiene gave achiral product, (E)- and (Z)-3-pentenal, in up to 95% selectivity. (R)-(E)-2-Methyl-3-pentenal was formed as the major product from both (E)- and (Z)-1,3-pentadiene, but enantioselectivity of the reaction was low. Mechanistic aspects are also discussed.

Asymmetric hydroformylation of conjugated dienes catalysed by [(R)-2-diphenylphosphino-1,1′-dinaphthalen-2′-yl] [(S)-1,1′-dinaphthalene-2,2′-diyl]phosphite-rhodium(I)

Asymmetric hydroformylation of conjugated dienes such as vinylcyclohexene, (E)-phenyl-buta-1,3-diene and 4-methyl-penta-1,3-diene using BINAPHOS-RhI complexes as catalysts {(R,S)-BINAPHOS = [(R)-2-diphenylphosphino-1,1′-dinaphthalen-2′-yl] [(S)-1,1′-dinaphthalene-2,2′-diyl]-phosphite} gives optically active β,γ-unsaturated aldehydes in high regio- (81-91%) and enantio-selectivities (84-97% ee).
