Abstract
Over the last decade my research group developed some efficient catalytic methodologies in the area of N-acyliminium ion chemistry. Those methods are largely contingent to the use of Brønsted and Lewis superacidic catalysts of the triflate and triflimidate family to activate and enable effective alkylations of cyclic N,O-acetals as N-acyliminium precursors. Driven by the current societal stakes to develop sustainable chemistry with the respect of atom- and step economy principles as the guidelines, recently we particularly endeavored to integrate our catalytic N-acyliminium processes into more complex, sequential events. This talk will illustrate our efforts in designing cascade and multicatalytic transformations that provide a wide array of relatively sophisticated polyanellated structures from trivial cyclic N,O-acetals with general good efficiency.
