The first example of asymmetric cyclization-carbonylation of 2-propargyl-1,3-dione 1 catalyzed by palladium(II) with chiral bisoxazolines (C.H.-BOX) was investigated. The use of bulky alcohols increased the ee of the products 2. The product 2d was converted into bicyclic enones 7 and 8, a useful intermediate for the synthesis of natural products.
