ABSTRACT

Asymmetric intermolecular hydroacylation between salicylaldehyde (1) and 1,5-hexadiene (2) using a combination of [RhCl(C(8)H(14))(2)](2) (0.10 eq), (S)-BINAP (0.10 eq), and ZnBr(2) (0.20 eq) afforded an enantiomerically enriched hydroacylated product iso-3 of 84% ee, along with an achiral product normal-3.
