Five- and six-membered cyclic amino acids can be prepared in good yield with high ee (>95%)
via tandem rhodium-DuPHOS catalysed asymmetric hydrogenation followed by a rhodium-catalysed hydroformylationâcyclisation sequence in a single pot. The synthesis can be achieved using Rh-DuPHOS as the sole catalyst.
