General Methods for Chemical Synthesis. 1 H NMR and 13 C NMR spectra were recorded on a JEOL ECA-500 (500 MHz) spectrometer using trimethylsilane as the internal standard, unless otherwise noted. ESI-TOF Mass spectra were measured on a Waters LCT premier XE. Silica gel TLC and column chromatography were performed using Merck TLC 60F-254 (0.25 mm) and Silica Gel 60 N (spherical, neutral) (Kanto Chemical Co., Inc.), respectively. Air-and/or moisture-sensitive reactions were carried out under andoi:10.1039/c0md00075b fatcat:dg2btwhz2fbfzpx6mmhq5m73ze
