Samarium iodide converts the β-silylacryalte 1c with high stereoselectivity into the racemic diester 2c, from which (±)-deoxyribonolactone 11 can be prepared.

Samarium iodide reacts with methyl (Z)-3-dimethyl(4-methylphenyl)silylprop-2-enoate 5b to give dimethyl (3RS,4SR)-3,4-bis[dimethyl(4-methylphenyl)silyl]hexane-1,6-dioate 8b with high stereoselectivity. This meso diester can be converted into (3RS,4SR)-3,4-bis[dimethyl(4-methylphenyl)silyl]pentan-5-olide 16 by Dieckmann cyclisation, demethoxycarbonylation and Baeyer–Villiger reaction.
