Asymmetric Total Synthesis of (+)‐Neooxazolomycin Using a Chirality‐Transfer Strategy

The total synthesis of (+)‐neooxazolomycin was achieved from the amino‐acid d ‐serine. The efficiency of this approach is derived from the use of principles of memory of chirality and dynamic kinetic resolution in the intramolecular aldol reaction of a serine derivative to build the densely functionalized lactam framework and to install three contiguous stereocenters. The key intermediate was readily elaborated to the target natural product.
