N-Imination of Boronic Acids and Organostannanes with O-Acyl Ketoximes

Significance

The reaction of oxime O-carboxylates with boronic acids or organostannanes grants a novel and easy synthetic access to the class of imines. It displays a broad functional group tolerance including even the very sensitive aldehydic and phenolic groups. The stereochemistry of this reaction, however, has yet to be improved.
