Additions of silyl enol ethers 3, 6, and 8 to chiral β-formyl esters 1 in the presence of TiCl4 provide trans-γ-lactones 4, 7, and 9 in high yield and with good to excellent diastereofacial selectivity.This high trans-preferrence is due to effective chelate-control involving seven-membered ring 1-TiCl4 complexes.
