phthalides by using enantioselective ketone hydroacylation. In the presence of Rh[(Duanphos)]X (X = NO(3), OTf, OMs), various 2-ketobenzaldehydes undergo intramolecularhydroacylation to produce phthalide products in good yields and 92-98% ee's. Our study highlights the key role counterions play in controlling both reactivity and enantioselectivity. A concise asymmetric total synthesis of the celery extract
