Introduction of functionalized C1, C2, and C3 units to imines was achieved by using the dimethylzinc-air-initiated α-alkoxyalkyl radical addition as a key reaction. The addition to a C:N double bond chemoselectively occurred in the presence of a C:O double bond, which is one of the advantages of this radical addition reaction over ionic addition reactions. The dimethylzinc-mediated reaction of 4-methyl-N-(phenylmethylene)benzenesulfonamide (I) with 2,2-dimethyl-1,3-dioxolane gave rel-N-[(R)-[(4R)-2,2-dimethyl-1,3-dioxolan-4-yl](phenyl)methyl]-4-methylbenzenesulfonamide (II) as the major product. Hydrolysis of II gave rel-N-[(2R,3R)-2,3-dihydroxy-1-phenylpropyl]-4-methylbenzenesulfonamide (III).
