expected branched-chain functionalised carbohydrates. An alternative route for compound 11, derived from the epoxide 9, consists of the deprotonation of the chlorohydrin 12 followed by the same protocol of lithiation-reaction with an electrophile. The application of this methodology to the oxetane 4 allows compound 6 to be obtained through the corresponding γ-functionalised organolithium intermediates 5.
