A sequence which combines a nonracemic tether, a naphthyl diol, and an aminonaphthol has been developed leading to the new ligand cyclo-NOBIN, which can easily be mounted onto polystyrene. Opportunities for extending the route to substituted cyclo-NOBINs are also discussed. 相似文献

A rhodium-catalyzed ortho-CH functionalization and annulation between enaminones and sulfoxonium ylides was developed, affording a series of multi-substituted naphthalenes in good to moderate yields with excellent functional group compatibility. The procedure featured with enaminone acting as both a directing and cyclization bifunctional group, and the application of sulfoxonium ylide in CH functionalization. 相似文献
