General Information. 1 H and 13 C NMR spectra were recorded in CDCl 3 with TMS as the initial standard on JEOL JNM- LA400 spectrometer. The following abbreviations were used to explain multiplicities: s, singlet; d, doublet; t, triplet; m, multiple. TLC analysis was carried out with Merk Silica Gel 60 F254 plates, detection of compounds was achieved by UV absorption (254 nm) and by charring after spraying with ceric ammonium sulfate in 10% aqueous H 2 SO 4 . Column chromatography was performed with Kieselgel 60 Silica Gel (Merk, 0.04-0.063 mm). All reagents and solvents were purchased from Kanto
