First ever synthesis of functionalized 5,7-dihydro-6H-dibenzo[d,f][1,3]diazepin-6-ones (6, 9) has been developed through base induced ring transformation of 2H-pyran-2-one-3-carbonitriles with indolin-2-ones. A protocol for alkenylating indolin-2-ones by 2H-pyran-2-one-3-carbonitriles has also been developed to obtain 3-alkenylindolin-2-ones (11). The nature and behaviour of intermolecular interactions
首次合成官能化5,7-二氢-6-的ħ -二苯并[ d,˚F ] [1,3]二氮杂卓-6-酮(6,9)已经通过的2个碱基诱导环转化开发ħ吡喃-2- -吲哚-2-酮的三甲腈。还已经开发了用于通过2 H-吡喃-2-酮-3-甲腈对吲哚-2-酮进行烯基化的方案,以获得3-烯基吲哚-2-酮(11)。通过单晶X射线分析和量子化学计算研究了这些化合物的分子间相互作用的性质和行为。
