Divergent synthesis is extremely important for the highly efficient preparation of structurally diverse target molecules. Herein, we describe a multicomponent cascade reaction, which allows access to highly substituted pyridines and benzenes by combining four individual steps in a one-pot manner from the same set of readily available starting materials. The azepine intermediates were first used as

A method is provided for the transition metal-catalyzed arylation, or vinylation, of hydrazines, hydrazones, and the like. Additionally, the invention provides a conceptually novel strategy, the cornerstone of which is the transition metal-catalyzed arylation or vinylation method, for the synthesis of indoles, carbazoles, and the like. The methods and strategies of the invention may be utilized in standard, parallel, and combinatorial synthetic protocols.
