Stereoselective synthesis of polyoxygenated linear diaza-triquinanes via intramolecular 1,3-dipolar cycloaddition of sugar-derived hex-5-enals
摘要:
An efficient and stereoselective synthesis of diaza-triquinanes, the skeleton structures of many natural products, has been accomplished by intramolecular 1,3-dipolar cycloaddition of azomethine imine generated from sugar-derived hex-5-enal and pyrazolidin-3-one.
