Desymmetrizinghydroformylation of bisalkenyl- and bisallylcarbinols could be achieved employing a chiral substrate-bound catalyst-directinggroup (o-DPPF) with excellent levels of diastereotopic alkene face and diastereotopic alkene group discrimination to give bifunctionalized chiral aldehydes in enantiomerically pure form.
