Abstract
Highly regioselective 5-exo bromolactonizations of stilbene-type carboxylic acids bearing electron-withdrawing substituents are achieved for the first time via the use of chiral bifunctional sulfide catalysts possessing a urea moiety. The chiral phthalide products are obtained in moderate to good enantioselectivities as the result of 5-exo cyclizations.

- 12 Asymmetric Bromolactonizations; General Procedure A solution of substrate 1 (0.10 mmol) and catalyst (S)-4d (10 mol%, 0.010 mmol) in CH2Cl2 (2 mL) was cooled to 0 °C. After stirring for 10 min, N-bromosuccinimide (NBS) (0.12 mmol) was added and the resulting mixture was stirred for 24 h at 0 °C. The mixture was quenched with saturated aqueous Na2SO3 (4.0 mL) at 0 °C, stirred for 10 min at 0 °C, diluted with CH2Cl2 (2 mL) and H2O (2 mL) and then warmed to room temperature. The organic materials were extracted with CH2Cl2 (3 × 5 mL) and the combined extracts dried over Na2SO4 and concentrated. (The 1H NMR analysis of the crude reaction mixture was performed at this stage to determine the regioselectivity of the bromolactonization products.) The residue was purified by flash column chromatography on silica gel (hexane/EtOAc as eluent) to give product 2. The enantioselectivity of the product 2 was determined by HPLC analysis on a chiral stationary phase.
