Five Easy Pieces. The Total Synthesis of Phosphoiodyn A (and Placotylene A)
摘要:
The convergent total synthesis of the marine natural product phosphoiodyn A, a nanomolar agonist of human peroxisome proliferator-activated receptor delta (hPPARd), was achieved in five steps total from commercially available and inexpensive starting materials. The synthesis relies on the unprecedented regioselective hydrozirconation of a terminal acetylene in the presence of a conjugated 1,3-diyne and on ammonolysis of a beta-chlorophosphonic acid monoester. The scheme also provides the newly isolated placotylene A, an inhibitor of bone marrow-derived macrophage (BMM) differentiation.
