Rapamycin (1) is a macrocyclic natural product, established as a potent immunosuppressant and currently of interest to the scientific community as the framework for a series of novel anticancer drugs. Extensive studies have culminated in a new convergent totalsynthesis of 1, which features a number of group‐derived methodologies and an unusual catechol‐templating strategy for the construction of the
approach to synthesize pitavastatin calcium (1), an effective HMG-CoAreductaseinhibitor, based on readily available and attractively functionalized (R)-3-chloro-1,2-propanediol is reported. This work highlights an intermolecular diastereoselective bromine-induced cyclization of homoallylic carbonate to meet stereochemical challenges in the synthesis of statins. An efficient route to a new triphenylphosphonium
