摘要
研究发现棉酚 3种异构体在CHCl3中同时存在着动态平衡 ,采用1 H 1 HCOSY ,1 H 1 3CHMQC以及HMBC等 2DNMR技术对这一新的现象进行了确证 ,并对它们的1 H和1
Three tautomers of gossypol, aldehyde (I), lacto (II) and ketal (III), exist in CDCl\-3, and are in equilibrium. 1H NMR spectra of the three tautomers were assigned by means of 1D and 2D NMR techniques including \{\}\+1H \+1H COSY, DEPT, HMQC (\+1H Detected Heteronuclear Multiple Quantum Coherence) and HMBC (\+1H Detected Heteronuclear Multiple Bond Connectivity) experiments.
