Abstract

Abstract: In this paper, the hydrogen transfer of gossypol and its imino derivatives (dianilinogossypol, dipyrimidinyliminogossypol and di-n-butyliminogossypol) in various solvents (CDCl₃,DMSO-d₆,C₆D₆,CD₃COCD₃ and 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.

Key words: NMR, Gossypol, Hydrogen Transfer, Tautomcr
