✦ Synopsis

Stereoselective hydroformylation and stereoselective conjugate addition to enoates has been achieved in a synthetic sequence employing a substrate-bound catalyst directing the o-DPPB group (o-DPPBsortho-diphenylphosphanyl benzoate). Furthermore, a stereoselective domino process combining hydroformylation, Wittig olefination and a transition metal catalyzed hydrogenation is described.

## Abstract The desymmetrizing hydroformylation of diallylcarbinols has been achieved by employing a planar‐chiral, substrate‐bound catalyst‐directing group β€” the __ortho__‐(diphenylphosphanyl)ferrocenylcarbonyl group (__o__‐DPPF). The method allows the simultaneous construction of two stereogenic
