A method for the synthesis of derivatives of 1-methylcarbapentofuranoses was developed. 1,2-cis- and 1,2-trans-4-hydroxymethyl-1-methylcyclopentanediols were obtained from intramolecular opening of 4-epoxy-4-methyl-γ-lactone. 1,3-cis- and 1,3-trans-4-hydroxymethyl-1-methylcyclopentanediols were obtained from intramolecular aldol reaction of 4-methyl-4-(2-oxoethyl)-γ-lactone derivatives.
