羽扇烷型化合物的核磁共振谱特征

THE CHARACTERISTICS OF ~1H AND ^(13)C NUCLEAR MAGNETIC RESONANCE OF LUPANE-TYPE TRITERPENES

核磁共振氢谱和碳谱(~1HNMR,^(13)CNMR)是天然有机化学研究领域不可缺少的工具,它在分析、鉴定化合物的结构以及探讨反应机理等方面已日益显示出其巨大威力。羽扇烷型化合物是广泛存在于自然界的三萜类化合物中的一大类。对这一类型结构进行专门性、系统性的核磁共振谱(尤其是^(13)CNMR)的研究尚未见报道,本文对此进行了一些探讨。

1H and (13)C Nuclear Magnetic Resonance are indispensable tools in natural organic chemistry. The tremendous power has been shown in structual determination of compounds and explorations of machanism in chemical reactions day by day. In this paper, the 1HNMR and 13C NMR about Lupane-type triterpenes which havn' t been previously reported systematically, have been summarized.
