o‐tolualdehyde tert‐butylimines were shown to condense with nitriles to form eneamido anion intermediates that were trapped in situ with various electrophiles, thus affording a diverse array of highly substituted isoquinolines, many of which are difficult to access by known methods. Further substitutional diversification was achieved by modification of the work‐up conditions and by subsequent transformations.
锂化 邻甲苯醛 叔丁基亚胺与腈缩合形成烯酰胺阴离子中间体,这些中间体被各种亲电子试剂原位捕获,从而提供多种高度取代的异喹啉,其中许多难以通过已知方法获得。通过修改后处理条件和随后的转化,实现了进一步的替代多样化。
