The melting points of the products were determined on a XT-4 binocular microscope (Beijing Tech Instrument Co., China) and were not corrected. The IR spectra were recorded on a Bruker VECTOR22 spectrometer in KBr disks.1H and13C NMR (solvent DMSO-δ6) spectra were recorded on a JEOL-ECX 50 0 NMR spec-trometer at room temperature using TMS as an internal standard.Elemental analysis was performed on an Elementar Vario-III CHN analyzer. UV spectra were recorded on a VARIAN Cary-50 spec-trometer using a cell path length of 1 cm. BIO-RAD, Model 6 80 Microplate Reader. The reagents were all of analytical grade orchemically pure. Analytical TLC was performed on silica gel GF254. 原文1.jpg [ Last edited by AnnF on 2012-12-31 at 12:45 ] |

| 产物熔点采用XT-4型双目显微镜测定（北京科技仪器公司，中国），不予校正。红外光谱（IR）通过溴化钾（KBr）压片以Bruker 公司VECTOR22型光谱仪记录。1H和13C的NMR(溶剂DMSO-d6)谱在常温下以JEOL-ECX500型 NMR光谱仪记录，TMS为内标。元素分析在Elementar Vario-III CHN元素分析仪上进行。紫外光谱通过VARIAN Cary-50型光谱仪记录，采用1cm长的比色皿，BIO-RAD680型酶标仪。所有试剂均为分析级或化学纯。薄层色谱分析（TLC）在GF254硅胶上进行。 |
