Significance
The cationic palladium complex was shown to be a good catalyst for the tandem annulation of 2-formylarylboronic acid and allenoates to produce indenol derivatives with good yield and diastereoselectivity. The use of chiral diphosphine ligands also provided good enantioselectivities for this novel transformation.
