The signals were referenced to residual chloroform (7.26 ppm, H, 77.00 ppm, 3 C). Chemical shifts are reported in ppm, multiplicities are indicated by s (singlet), d (doublet), t (triplet), q (quartet) and m (multiplet). Melting points are uncorrected and were determined on a Büchi melting point apparatus. IR spectra were obtained with a FTIR spectrometer (JASCO FT/IR-400). Optical rotations were measured using a Polarotronic polarimeter (Schmidt & Haensch). All ESI mass spectra were recorded on a Brucker ESI-TOF microtof. HPLC analyses were carried out on a Jasco MD-200 plus or Jasco MD-405 instrument with chiral stationary phase column (Daicel Chiralpak IA column). tert-butyl methyl ether and hexane were technical grade and distilled from KOH, toluene was purified and dried by a Solvent Purification System MB SPS-800 (Braun). Flash column chromatography was performed by using Merck silica gel 60 230-400 mesh (0.040-0.063 mm). All reactions were monitored by thin layer chromatography using precoated silica gel plates. Spots were visualized by UV (λ = 254 nm) and were treated with a vanillin solution in methanol (technical grade). 2-Vinyl indoles 5 were known and prepared by following the literature procedure. [] X-ray data were collected with a GEMII CCD diffractometer (Rigaku Inc.), λ(mo-kα) = 0.7073 Å, T = 30(2) K, empirical absorption corrections with SCALE3 ABSPACK. [2] The structure was solved by dual space methods with SIR-92. [3] Structure refinement was done with SHELXL-206 [4] by using full-matrix least-square routines against F2. All hydrogen atoms were calculated on idealized positions with exception of the OH proton which was detected in the difference map and refined with a restraint. The absolute structure was established by anomalous dispersion effects. The picture was generated with the program ORTEP.

Experimental procedures General procedure A: Enantioselective Cycloaddition To a suspension of (H-pyrrol-2-yl)(aryl)methanol 4 (0.2 mmol,.2 equiv), (E)-3-methyl-2-(styryl)-H-indole 5 (0. mmol, equiv) and pulverized 4 Å molecular sieves (30 mg, 300 mg/mmol) in toluene ( ml), catalyst 7g (6.3 mg, 0.0 mmol, 0 mol%) was added at rt. The reaction mixture was stirred at 60 C and monitored by TLC. After completion of the reaction the crude reaction mixture was purified by column chromatography using hexane-mtbe (0.5-0 %, gradient elution) as eluent to afford products 6/8. The enantiomeric excess was determined by HPLC on a chiral stationary phase. Diastereomeric ratio was determined via H-MR and was >20: in all cases. Large scale synthesis: Analogous to General Procedure A the reaction was performed using 4h (.62 g, 4.80 mmol,.2 eq.), 5a (933 mg, 4.00 mmol,.0 eq.),.0 g pulverized 4 Å molecular sieves and catalyst 7g (23 mg, 0.200 mmol, 5 mol%) in toluene (40 ml) and gave product 6h in 89 % yield (.95 g) and 96:4 e.r. The enantiomeric ratio was further enhanced to >99.5:0.5 e.r. by single recrystallization. General procedure B: Photocatalytic Autooxidation 3-(3-Methyl-H-Indol-2-yl)-2,3-dihydro-H-pyrrolizine 6 (0.0 mmol,.0 eq.) was dissolved in toluene and 0.5 mg (> mol%) rose bengal was added. A continuous stream of oxygen was bubbled through the reaction mixture and it was irradiated with green LEDs for 4 h. The precipitate was collected, washed with hexanes and dried under reduced pressure to give hydroperoxide 9 as pale pink solid.
