Remodeling of Fumagillol: Discovery of an Oxygen-Directed Oxidative Mannich Reaction
摘要:
An efficient, two-step construction of highly complex alkaloid-like compounds from the natural product fumagillol is described. This approach, which. mimics a biosynthetic cyclase/oxidase sequence, allows for rapid and efficient structure elaboration of the basic fumagillol scaffold with a variety of readily available coupling partners. Mechanistic experiments leading to the discovery of an oxygen-directed oxidative Mannich reaction are also described.

synthetic strategies break through the limitation of traditional librarysynthesis by sampling new chemical space. Many natural products can be regarded as intriguing starting points for diversity-oriented synthesis, wherein stereochemically rich core structures may be reorganized into chemotypes that are distinctly different from the parent structure. Ideally, to be suited to library applications, such transformations
