Supporting Information Asymmetric Binary-acid Catalysis with Chiral Phosphoric Acid and MgF 2 : Catalytic Enantioselective Friedel-Crafts Reactions of β,γ- Unsaturated-α-Ketoesters Jian Lv, Xin Li, Long Zhang, Sanzhong Luo,* Jin-Pei Cheng Beijing National Laboratory for Molecular Sciences (BNLMS), CAS Key Laboratory of Molecular Recognition and Function, Institute of Chemistry, the Chinese Academy of Sciences, Beijing 100080, China E-mail: luosz@iccas.ac.cn General Information: Commercial reagents were used as received, unless otherwise indicated. 1 H, 13 C, NMR spectra were measured on a NMR instrument (300 MHz for 1 H NMR, 75 MHz for 13 C NMR). Tetramethylsilane (TMS) served as the internal standard for 1 H NMR, and CD 3 served as the internal standard for 13 C NMR. The following abbreviations were used to express the multiplicities: s = singlet; d= doublet; t = triplet; q 1
= quartet; m = multiplet; br = broad. HPLC analysis was performed using Chiralcel columns purchased. General Procedure for Asymmetric Friedel-Crafts Alkylation of β,γ-unsaturated-α- Ketonesters: To a flame-dried Schlenk tube was added MgF 2 (0.005 mmol, 5 mol%), (S)-1a (0.020 mmol, 20 mol%) and 4 Ǻ M.S. (40 mg). The mixture was dried under vacuum for 0.5 h and distilled anhydrous CH 2 2 (1.5 ml) was added under Ar. After stirring for 0.5 h, 3a (0.10 mmol) in CH 2 2 (0.25 ml) was added and the mixture were cooled to -70 C. After addition of 2a (0.12 mmol) in CH 2 2 (0.25 ml), the mixture was stirred for 48 h at -70 C. Purification of the mixture by column chromatography on silica gel with DCM-ethyl acetate (25:1) as eluent gave 4a as a colorless oil (24.8 mg, 79%). The enantiomeric ratios of the product were determined by chiral HPLC analysis using a chiral column. Compound 4k, 1 4o, 2 4q 1 and 4r 1 are known compounds. The absolute configurations of other products including the phenol products are determined by analogy with these known compounds.
