[structure: see text] Synthesis of gamma-amino acids, important building blocks in bioorganic and natural product chemistry, is accomplished using a stereoselective carbon-carbon bond construction of the chiral amine. Alkyl iodides and chiral hydrazones with protected alcohol functionality are coupled via highly diastereoselective photolytic Mn-mediated addition to the C=Nbond, providing access to
