General Information Unless otherwise stated, all reagents were purchased from commercial suppliers and purified prior to use. Racemic amines were purchased from Aldrich, abcr and TCI. Diketones were purchased from Aldrich and abcr. All solvents used in the reactions were distilled from appropriate drying agents prior to use. Reactions were monitored by thin layer chromatography (TLC) on silica gel pre-coated plastic sheets (.2 mm, Macherey-Nagel). Visualization was accomplished by irradiation with UV light at 4 nm and/or KMnO 4 stain. Neutral Al 2 O 3 (Type I) was purchased from Aldrich. Column chromatography was performed on neutral Al 2 O 3 (Type III). Proton and carbon NMR spectra were recorded on a Bruker AV- 5 spectrometer in deuterated solvents. Proton chemical shifts are reported in ppm (δ) relative to tetramethylsilane (TMS) with the solvent resonance employed as the internal standard (CDCl 3 δ 7.26 and CD 2 Cl 2 δ 5.32 ppm). Data are reported as follows: chemical shift, multiplicity (s = singlet, d = doublet, t = triplet, q = quartet, p = pentet, s = sextet, h = heptet, m = multiplet, br = broad), coupling constants (Hz) and integration. 13 C chemical shifts are reported in ppm from tetramethylsilane (TMS) with the solvent resonance as the internal standard (CDCl 3 δ 77.16 and CD 2 Cl 2 δ53.84 ppm). High resolution mass spectra were determined on a Bruker APEX III FTMS (7 T magnet). Optical rotations were determined with an Autopol IV polarimeter (Rudolph Research Analytical) at 589 nm and C. Data are reported as follows: [α] temp λ, concentration (c in g/1 ml), and solvent. Enantiomeric ratios (er) were determined by HPLC analysis employing a chiral stationary phase column specified in the individual experiment, by comparing the samples with the appropriate racemic mixtures.

1a. General Procedure for the Kinetic Resolution of rac-amines for Table 1 An oven-dried 2 ml GC vial was charged with catalyst 3 (5 mol%,.5 equiv.,.1 mmol) and a magnetic stirring bar. To this vial Et 2 O (. ml) was added followed by racamine (1. equiv.,. mmol, 3.2 µl) under argon atmosphere. The mixture was then stirred at rt for 5 min. 5Å Molecular sieve ( mg) was then added and the mixture immediately cooled to 78 C. To the mixture, diketone 2 (.55 equiv.,.14 mmol) was added under argon atmosphere. The reaction vial was warmed to 5 C. After 2 h, the reaction was quenched with triethylamine (.5 equiv.,.1 mmol, 1.7 µl) and benzoic anhydride (.45 equiv.,.112 mmol, 2.5 mg) was added. It was further stirred at rt for 3 min. The crude mixture was directly purified without further work-up on SiO 2 preparative TLC using 5% Et 2 O/DCM (v/v) and 2% EtOAc/i-Hexane as eluents for product 4 and benzoylated derivative 5a respectively. 1b. General Procedure for the Kinetic Resolution of rac-amine for Chart 1 An oven-dried 4 ml vial was charged with catalyst 3c (5 mol%,.5 equiv., 5.36 mg) and a magnetic stirring bar. To this vial Et 2 O (.8 ml) was added followed by rac-amine (1. equiv.,.1 mmol) (Note 1) under argon atmosphere. The mixture was then stirred at rt for 5 min. 5Å Molecular sieve (1 mg) was then added and the mixture immediately cooled to 78 C. To the mixture, diketone 2c (.55 equiv.,.55 mmol, 6.4 µl in.2 ml Et 2 O) (Note 2) was added through the cold side-wall of the vial under argon atmosphere. The reaction vial was warmed to 5 C and was stirred for 24 h (Note 3). After 24 h, the reaction was quenched S3
with triethylamine (.6 equiv.,.6 mmol, 8.4 µl) and benzoic anhydride (.5 equiv.,.5 mmol, 11.4 mg) was added. It was further stirred at rt for 3 min. The crude mixture was directly purified without further work up (Note 4). Purification was performed on neutral Al 2 O 3 (Type III) using % Et 2 O/Pentane (v/v) to 5% Et 2 O/Pentane (v/v) as eluent. The products 4 were obtained as light yellow oils and the benzoylated products 5 were obtained as white solids. Note 1: It was found that the rac-amines form white solids upon exposure to air. These were freshly distilled and stored in Schlenk flasks under argon atmosphere prior to use. Note 2: Diketones were freshly distilled and stored in Schlenk flasks under argon atmosphere prior to use. It was found that the diketones turn yellow over time. The unknown yellow impurities can be removed under high vacuum (5x1-2 mbar at rt for 1 min). Note 3: A proper stirring for the reaction mixture is needed due to high loading of Molecular sieve. Typically, the raction mixture was stirred at 4 5 rpm speed. Note 4: Due to the low stability of the products 4 on SiO 2, purification was performed using neutral Al 2 O 3 (Type III). 1c. Procedure for the Large Scale Experiment An oven-dried ml flask was charged with catalyst 3c (1 mol%,.1 equiv., 94. mg) and a magnetic stirring bar. To this vial Et 2 O (7 ml) was added followed by rac-amine (1. equiv., 8.7 mmol, 1. g) under argon atmosphere. The mixture was then stirred at rt for 1 min. 5Å Molecular sieve (9 g) was then added and the mixture immediately cooled to 78 C. To the mixture, diketone 2c (.55 equiv., 4.8 mmol,.56 ml in 17 ml Et 2 O) was added through the cold side-wall of the vial under argon atmosphere over 1 min. The reaction flask was warmed to 5 C and was stirred for 5 d. After 5 d, the reaction was quenched with triethylamine (.6 equiv., 5.2 mmol,.73 ml) and benzoic anhydride (.5 equiv., 4.3 mmol, S4
.98 g) was added. It was further stirred for 1 h and then 3 min at rt. The crude mixture was directly purified without further work up as a solid-load over celite. Purification was performed on neutral Al 2 O 3 (Type III) using 2% Et 2 O/Pentane (v/v) to 5% Et 2 O/Pentane (v/v) as eluent. The product 4g was obtained as light yellow oil in 41% isolated yield and the benzoylated product 5g was obtained as white solid in 46% isolated yield. Deprotection step: A 4 ml vial was charged with 4g (42. mg,.2 mmol, er = 6:94) and a magnetic stirring bar. To this vial MeOH (.4 ml) was added followed by NH 2 OH.HCl (1.2 equiv.,.24 mml, 16.7 mg). The reaction mixture was stirried at rt for 1.5 h and MeOH was removed. The crude product was dissolved in.5 ml of CH 2 Cl 2 and Et 3 N (1.3 equiv.,.26 mmol, 36. µl). It was then cooled to C and benzoic anhydride (1.2 equiv.,.24 mmol, 54 mg) was added. The reaction mixture was stirried at rt for 3 min. The benzoylated product was purified on SiO 2 preparative TLC and the ee was determined by HPLC (er = 6:94). 1d. Pyrrole formation from 1,4-diketone An oven-dried GC vial was charged with catalyst 3a (1 mol%) and a magnetic stirring bar. To this vial PhMe (. ml) was added followed by rac-amine (1. equiv.,. mmol). To the mixture, diketone (.5 equiv.,.12 mmol) was added and the vial was cooled to 2 C and was stirred for 13 d. The s factor was determined as above. S5
2. Determination of the s-factor: Conversion (C) was determined by measuring the ee of both the product and the benzoylated derivative of the unreacted recovered starting material by HPLC. ee p is the enantiomeric excess of the product and ee SM is the enantiomeric excess of the recovered unreacted starting material. The s-factor can be calculated using the calculated conversion. 1 3. Determination of the Absolute Configuration: The absolute configuration of 4a was determined by HPLC trace comparison with the commercially available enantio-pure (R)-1a. The absolute configuration of 4i was determined by HPLC trace comparison with the commercially available enantio-pure (R)-1i. 1. Kagan, H. B.; Fiaud, J. C. Top. Stereochem. 1988, 18, 249. S6
