The Lewis acid mediated intramolecular Nicholas reactions of allylic acetate enyne-Co2(CO)6 complexes afford bicyclic- and tricyclic cycloheptenyne-Co2(CO)6 complexes.
A practical and efficient approach for the total synthesis of arucadiol and 1-oxomiltirone is reported. The key step which involves an intramolecular [4+2] cycloaddition catalyzed by gold(III) bromide or copper(II) triflate leads to the formation of 6-6-6-fused aromatic abietane core.
