摘要

The biaryl unit is extensively presented in many classes of natural products, such as polyketides, terpenes, lignanes,coumarins, flavonoids, tannins, and many alkaloids.[1] It has long been recognized that an intramolecular oxidative phenolic or nonphenolic coupling reaction serves as the key step in the biosynthesis of these natural products, and the non-enzymic analogue of this transformation can lead the elegantly simple syntheses of these compounds.[2] During the last decade, a large number of oxidative coupling reagents, such as ferric chloride (FeCl3), phenyliodine(Ⅲ)bis(trifluoroacetate) (PIFA), lead(Ⅳ) tetraacetate [Pb(OAc)4], thallium(Ⅲ) triflouroacetate (TTFA), as well as vanadium oxytrifluoride (VOF3),[3,4] have been developed for this target. However, extensive application of this synthetic potential has been limited by low yields and unexpected side reactions usually encountered.……
