Abstract

In conjunction with ongoing efforts in our laboratories aimed at the application of environmentally benign clays in organic synthesis, we have developed a convenient clay-catalyzed route to benzopyran derivatives that may be applied in the synthesis of benzopyran-containing natural products. Although clays have been shown to successfully catalyze a variety of organic reactions, [4] they are somewhat under-exploited in natural products synthesis, [5] perhaps because their specific modes of ...
