Abstract
The Pd-0-catalyzed alkylation of 1 by sodiodimethylmalonate led to the form ation of two tricyclic diastereomers 2a and 2b. The structure of the major endo diastereomer 2b has been confirmed by NMR experiments and X-ray struct ure analysis. This stereochemistry is in accordance with the formation of a n exo cationic (pi -allyl)palladium intermediate.
