Abstract

The Lewis acid-mediated chelation control is one of the most fundamental and practically important concepts in modern organic chemistry. 1 It is well accepted that the chelating controlled reaction proceeds through the coordination of a Lewis acid to a lone pair of heteroatoms, such as an oxygen of aldehydes and a nitrogen atom of imines. To the best of our knowledge, there is no precedent for a synthetically useful level of the ...
