Ailanthoidol 1, which can be isolated from Chinese herbal medicine, is achieved in which the longest linear sequence is only six steps in 48% overall yield from commercially available 5-bromo-2-hydroxy-3-
methoxybenzaldehyde 9. The key transformations in the synthesis are the Stille coupling reactions of benzofuranyl bromide with stannanyl compounds. The synthetic strategy can be modified to give access to a variety of different ailanthoidol and XH-14 analogues.
A particularly elusive, yet attractive, goal has been the formation of stable molecular networks with nanometre-scale voids. According to the concept of molecularly-based zeolites, we have reported the remarkable 3-D network, which contains the chelating coordination of highly D3h symmetry sexipyridine analogues with metal complex and that preparation of the target compound by use of palladium couplings. In addition, acetylene-bridged pyridines will be accessible via palladium coupling protocols in our future work.
