Optically active α- and α,β-substituted aldehyde hydrazones 2, 4, and 7, which are readily available by asymmetric alkylation. Michael addition or [2,3]-Wittig rearrangement of chiral hydrazones can be transformed into nitriles 3 and 5 or cyanohydrins 8 by MMPP mediated oxidation, respectively. This synthetic sequence offers a C-C connective entry into optically active functionalised nitriles with
