All commercially available reagents and solvents were used without further purification. Preparative separation was usually performed by column chromatography on silica gel (F可isilysia L TD, B W・200and B W・.300)and on alminum oxide (Merck, Aluminum oxide 90, standardized, activity II‑III). 1H NMR and 13C NMR spectra were recorded on a JEOL か400spectrometer oraJNM占CX400KA spectrometer and chemical shifts were represented as ふvaluesrelative to the intemal standard TMS. IR spectra were recorded on a JASCO FTIIR・8000 Fourier Transform Infrared Spectrometer or a S兄 島 仏DZUFTIR柵8100AFourier Transform Infrared Spectrometer or a JASCO RT/IR 4200 Fourier Transform Infrared Spectrometer. Optical rotations were measured with a JASCO DIP欄370Digital Polarimeter. High resolution mass spectra (HRMS) were measured on either a JEOL JMふ T100LC or a JEOL JMS・‑700Tspectrometer.
