Abstract
First isolated from Sorangium cellulosum So ce 307, jerangolids are a class of natural products with high antifungal activity and minimal toxicity toward mammals. Comprised of a skipped diene substructure with a chiral center in between a δ-lactone and a pyran substituent, they present an intriguing synthetic challenge. We herein report the first synthesis of jerangolid B through a modular approach that incorporates sp3-sp2 Stille coupling as the key step to generate the skipped diene structure. By comparing our synthetic jerangolid B to the data published in the literature, we could show that the configuration at C14 is R.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
