The synthesis of the potential molecular receptors in the amination-reduction reaction has been investigated within the model system comprising (2-formylphenyl)boronic acid and morpholine. The 3-amine substituted benzoxaborole was identified to be the intermediate of the synthesis and the unsubstituted benzoxaborole as the by-product resulting from reduction of the starting material. The insight into the reactivity of the starting materials as well as the intermediate benzoxaborole enabled significant rise in the yield of 2-(aminomethyl) phenylboronic acids synthesis. The solid state structure of 2-(piperidylmethyl)phenylboronic acid has been re-determined, and the description of the molecule and the crystal is given. The supramolecular layer structure directed by the weak C-H...O and C-H...π interactions was identified and scrutinized based on the geometry and Hirshfeld surface analyses. Versita Sp. z o.o.
