We disclose the first synthesis of the marine natural product, (+)-boneratamide A, whose structure is composed of a terpene unit linkedivia/ian amide bond to a pyroglutamic acid moiety. The key step in this route is a bioinspired Ugi reaction of (+)-

A pathway is proposed for the biosynthesis of the unique homodimeric terpene, halichonadin H. The proposed biosynthetic pathway involves two key Passerini reactions of eudesmane-type terpene isocyanides. The Passerini reaction of a model terpene isoc

The first total synthesis of a marine natural product, exigurin, has been accomplished in 13 steps starting from (+)-menthone. The key intermediate (−)-10-epi-axisonitrile-3 was prepared by stereoselective intramolecular cyclopropanation followed b
