  摘要：

  A versatile synthesis of orthogonally protected derivatives of carba-alpha-D-glucosamine, carba-alpha-D-mannose, carba-alpha-D-mannuronic acid, carba-beta-L-idosamine, and carba-beta-L-gulose from methyl alpha-D-mannoside is described. Our synthetic strategy utilizes the palladium-promoted Ferrier carbocyclization and persistent butane-2,3-diacetal protection to produce a key chiral cyclohexanone intermediate, from which all five carbasugar derivatives can readily be obtained.
