摘要
用O -过乙酰基-α- d -吡喃基溴在干丙酮中处理4-萘基-3-氰基-2-硫代吡啶盐，为高产率合成2-(β- d -吡喃基)吡啶提供了一种简便的新方法。通过1h和13c核磁共振谱分析确定了吡啶环上的糖基化位点。
A facile synthesis of 4-naphthyl-3-cyano-2-(β-d-pyranosylthio) pyridines
The treatment of piperidinium salt of 4-naphthyl-3-cyano-2-thiopyridines with an O -peracetyl-α-D-pyranosyl bromide in dry acetone provides a new and simple method for the synthesis of 2-(β-D-pyranosylthio) pyridines in high yields. The site of glycosylation on the pyridine ring was confirmed by 1 H and 13 C NMR spectral analysis.
