| Abstract | General Experimental Procedures. All reactions were carried out under nitrogen except noted. Anhydrous dichloromethane (CH2Cl2) and 1,2-dichloroethane (DCE) were distilled from calcium hydride. Tetrahydrofuran (THF) was distilled from sodium-benzophenone ketyl, and anhydrous toluene was prepared from sodium. Flash column chromatography was performed as described by Still (Still, W. C.; Kahn, M.; Mitra, A. J. Org. Chem. 1978, 43, 2923–2925), employing Qingdao Haiyang silica gel 60 (200–300 mesh) TLC analyses were performed on EMD 250 m Silica Gel HSGF254 plates and visualized by quenching of UV fluorescence (λmax= 254 nm), or by staining ceric ammonium molybdate, ammonium molybdate, or potassium permanganate. 1H and 13C NMR spectra were recorded on a Bruker-500, 400 spectrometer. Chemical shifts for 1H and 13C NMR spectra are reported in ppm (δ) relative to residue protium in the solvent (CDCl3: δ 7.26, 77.0 ppm;) and the multiplicities are presented as follows: s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet. High-resolution mass spectra (HRMS) were acquired on a waters GCT premier. The photo reactor used for this photolysis is Rayonet RPR-200 (Southern New England Ultraviolet Company). |
