Abstract:(i)-Camphor-8-W was prepared by a reaction sequence involving l4C-carbonation of 3-methylnorbornanone, reaction of the product with methylmagnesium iodide, followed by rearrangement of the P-hy-droxy acid to 1, 7-dimethylnorbornane-7-carbo-2-lactone. Reduction of the lactone to a glycol followed by selec-tive oxidation of the secondary hydroxyl, replacement of the primary hydroxyl by bromine, and hydrogenolysis of the ...
