摘要
本文利用~1HNMR法研究棉酚及其胺类衍生物(双苯胺棉酚,双丁基棉酚和双嘧啶棉酚)在不同溶剂(CDCl_3,DMSO-d_6,C_6D_6,CD_3COCD_3,DMF-d_7 等)中和不同的酸碱环境下的氢转移(即结构互交).实验表明,棉酚、双苯胺棉酚、双丁基棉酚和双嘧啶存在着三种不同的异构体.这些异构体在同一溶剂不同环境下可以并存或者相互转变.
In this paper, the hydrogen transfer of gossypol and its imino derivatives (dianilinogossypol , dipyrimidinyliminogossypol and di-n-butyliminogossypol ) in various solvents ( CDCl3,DMSO -d6,D6CD3COCD3and DMF-d7) under different acidic or basic conditions was shudicd by 1H NMR method . Results show that , three different tautomers existed for each of the above mentioned gossypol imino derivatives , Moreover , the forms of these three tautomcrs are interchangable or co-exist in the same solvent under different conditions .
