Simple enantioselective routes to the two key intermediates shown above (at center) for the synthesis of laurenditerpenol have been developed using a Diels-Alder step and the same catalyst system for each.

This paper reports a method for highly enantioselective Diels−Alder reaction with an acetylene equivalent to produce chiral-bridged dienes. These dienes, by coordination to Rh(I), can serve as catalysts for the enantioselective addition of vinyl or aryl groups to α,β-unsaturated ketones.
