Treatment of stereodefined w-halo-2-iodoalkene derivatives (l), prepared via stereoselective addition reactions of alkynes, with either n\_BuLi (1 equiv) or t-BuLi (2 equiv) can produce exccyclic alkenes whose isomeric purity is essentially 100%.

A stereoselective method for the preparation of dibenzoxapine containing tetrasubstituted exocyclic E-alkenes has been developed. The key reaction involves an intramolecular cyclocarbopalladation of alkynes to form a vinylpalladium species and subsequently coupling the vinylpalladium with methylboro
The Garner aldehyde-derived methylene alkene has been hydroborated using 9-BBN and the resulting organoborane employed in palladiurn-catalysed Suzuki coupling reactions to produce, offer hydrolysis-oxidation, a range of novel amino acids as their N-BOC protected derivatives.
