Ni(II)-catalyzed Michael additions. Part 2: Dynamic kinetic resolution in the reduction of chiral α-hydrazino-β-ketoacid derivatives

Relative syn 1,2-hydrazinoalcohols have been prepared through diastereoselective Ni(II)-catalyzed Michael addition of chiral derivatives of acetoacetic acid and of 3-oxostearic acid to dialkyl azodicarboxylates, followed by stereoselective reduction of the keto function.
