cinchonia

Chiral quaternary ammonium salts were synthesized from cinchonine in cinchona alkaloids using chloromethylated polystyrene - polyethylene glycol , diethylene glycol , triethylene glycol and glycol as polymer - supported phase transfer catalysts , finsl products were characterized by ftir , elemental analysis , scanning electron microscopy , x - ray photoelectron spectroscopy ( xps ) 摘要以金雞納生物堿中的辛可寧為原料,氯甲基化聚苯乙烯聚乙二醇、一縮二乙二醇、二縮三乙二醇、乙二醇等為載體合成了幾種聚合物負載的手性季銨鹽,并對它們的結構用紅外光譜、元素分析、掃描電鏡和x射線光電子能譜等測試手段進行了表徵。
