要旨

Pyridine–oxazoline-type ligands (PyOX) are an important class of chiral ligands for metal-catalyzed asymmetric transformations. Herein we describe an efficient and reliable flow route which is amenable for the synthesis of PyOX ligands at a scale of hundreds of milligrams per hour. Optimal flow conditions were rapidly identified through the assistance of an in-house built autonomous self-optimizing system integrating a custom-made optimization algorithm derived from the Nelder–Mead and golden section search methods. The preparation of a small library of representative PyOX ligands highlights the practical application of this flow route which should be of primary interest for synthetic chemists developing metal-catalyzed asymmetric transformations.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
