Web1H and 13C NMR spectra were recorded on a JEOL JNM-ECA500 spectrometer in CDCl 3 unless otherwise noted. Trimethhylsilane (TMS) served as internal standard (δ = 0) for 1H NMR, and CDCl 3 was used as an internal standard (δ= 77.0) for 13C NMR analysis. IR spectra were measured with a JASCO FT/IR-4200 spectrometer.
