Unprecedented SmI2 mediated Dreiding-Schmidt reactions were used for chain extension reactions of aldonolactones with alkyl 2-bromomethyl acrylates or 2-bromomethyl-acrylonitrile, respectively. The reaction of aldonolactones with diiodomethane in the presence of samarium powder resulted in the formation of polyhydroxyalkyl substituted cyclopropanols.
