Abstract
Abstract 1, 5-Bismethylene cyclooctane 1 is transformed in a one pot multi step sequence to bridgehead substituted bicyclo [4. 3. 1] decane derivatives by a catalytical Pd II mediated oxidation reaction. A regioselective Wagner Meerwein rearrangement leading to ring enlargement is involved. The major product 5 can be fragmentated to a nine membered ring.
