Abstract
This article describes recent total synthesis of natural products, in which highly stereo-and regioselective reactions by internal chelation with metal salts are involved. The first part of the report presents a number of total syntheses of natural products, which use highly stereoselective carbon-carbon bond forming reactions by internal chelation with metal salts. In the second part, natural product synthesis, which involves highly stereoselective reductions by internal chelation, is discussed. The final two parts of the article present synthesis of natural products, in which chelation-controlled regioselective reactions are included.
