Abstract
An improved synthesis of the cyanthiwigin natural product core enabled by new catalytic technology is reported. The key double catalytic enantioselective alkylation has been reoptimized using a recently developed protocol employing low loadings of palladium catalyst, thereby facilitating large-scale production of the tricyclic cyanthiwigin framework. Additionally, preparation of the penultimate aldehyde intermediate is expedited through the application of anti-Markovnikov Tsuji–Wacker oxidation.
