Divergent synthesis of L-sugars and L-iminosugars from D-sugars

An efficient divergent synthesis of L-sugars and L-iminosugars from D-sugars is described. The important intermediate. δ-hydroxyalkoxamate. prepared from D-glucono-/galactono-1,5-lactone, was cyclized under Mitsunobu conditions to give the O-cyclized oxim

Synthesis of L-pyranosides from 5-enopyranosides by diastereoselective hydroboration/oxidation

Improved synthesis of L-pyranosides utilizing diastereoselective hydroboration/oxidation of 5-enopyranosides was investigated. A unique phenomenon in the diastereoselectivity of the hydroboration was incidentally found. The method was successfully applied to the synthesis of L-iduronic acid.
