Abstract

Five-membered oxygen-containing heterocycles are important structural components in a diverse range of naturally occurring and pharmacologically active molecules.[1] Their widespread occurrence in the structures of natural or artificial bioactive substances has stimulated considerable interest in the development of new, efficient preparation methods.[2] Among numerous known synthetic methods, the convergent annulation, which features ...
