应用1HNMR技术对一些以 [2 +4 ]环加成方式合成出的苯并二氮杂卓的立体化学进行了研究 .利用偶合常数和 gNOESY的结果 ,证明了二氮杂卓七员环的扭船式溶液构象 ,并与其类似的苯并硫氮杂卓作了比较和讨论 .
1HNMR was used to study the stereochemistry of some benzodiazepines synthesized by [2 +4] cycloaddition.Using the results of coupling constants and gNOESY, Ship solution conformation, and its similar benzothiazepine were compared and discussed.
