S1 The Direct Amino Acid-Catalyzed Asymmetric Incorporation of Molecular Oxygen to Organic Compounds Armando Córdova,* Henrik Sundén, Magnus Engqvist, Ismail Ibrahem and Jesús Casas Contribution from The Department of Organic Chemistry, Arrhenius Laboratory, Stockholm University, SE-10691Stockholm, Sweden Supporting Information General. Chemicals and solvents were either purchased puriss p.A. from commercial suppliers or purified by standard techniques. For thin-layer chromatography (TLC), silica gel plates Merck 60 F254 were used and compounds were visualized by irradiation with UV light and/or by treatment with a solution of phosphomolybdic acid (25 g), Ce(SO 4 ) 2 . H 2 O (10 g), conc. H 2 SO 4 (60 mL), and H 2 O (940 mL) followed by heating or by treatment with a solution of p-anisaldehyde (23 mL), conc. H 2 SO 4 (35 mL), acetic acid (10 mL), and ethanol (900 mL) followed by heating. Flash chromatography was performed using silica gel Merck 60 (particle size 0.040-0.063 mm), 1 H NMR and 13 C NMR spectra were recorded on Varian AS 400. Chemical shifts are given in d relative to tetramethylsilane (TMS), the coupling constants J are given in Hz. The spectra were recorded in CDCl 3 as solvent at room temperature, TMS served as internal standard (d = 0 ppm) for 1 H NMR, and CDCl 3 was used as internal standard (d = 77.0 ppm) for 13 C NMR. HPLC was carried out using a Waters 2690 Millennium with photodiode array detector. GC was carried out using a Varian 3800 gas chromatograph. Optical rotations were recorded on a Perkin Elemer 241 Polarimeter (l =589 nm, 1 dm cell). High
