A new series of 7-aryl-4,5-dmydro-2-oxo-3H,8H-furo[3,4-b][1,4] diazepines were prepared. Their lH nmr spectra have been interpreted in terms of the interconversion of two pseudo-boat conformers. Molecular-dynamics simulations at different temperatures on this type of compounds revealed a very small energy difference between these two conformers.
制备了一系列新的7-芳基-4,5-二甲基-2-氧代-3 H,8 H-呋喃[3,4- b ] [1,4]二氮杂pine 。它们的1 H nmr光谱已根据两个伪船构象异构体的互变进行了解释。这类化合物在不同温度下的分子动力学模拟表明,这两个构象异构体之间的能量差很小。
