Syntheses of anolignans A and B using ruthenium-catalyzed cross-enyne metathesis

Anolignans A and B were synthesized using ruthenium-catalyzed cross-enyne metathesis as the key steps. The 1,3-diene moieties of these natural products were constructed by the introduction of the methylene parts of ethylene into alkyne using Grubbs' catalyst.
