A general and highly efficient protocol for the synthesis of dibenzodiazepines and their structural analogues is reported. In the presence of catalytic quantities of palladium, readily accessible precursors are cross-coupled with ammonia and then spontaneously undergo an intramolecular condensation to form the corresponding dibenzodiazepines in one step. This new strategy is applicable to the construction
报告了合成二苯二氮卓类及其结构类似物的通用且高效的方案。在催化量的钯存在下,容易获得的前体与氨交叉偶联,然后自发地进行分子内缩合,一步形成相应的二苯二氮卓类。这种新策略适用于构建各种二苯并氧氮杂和其他结构相关的杂环。
