摘要

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. The key transformations in the synthesis are the Stille coupling reactions of benzofuranyl bromide with stannanyl compounds. This synthetic strategy can be modified to give access to a variety of different ailanthoidol and XH14 analogues.
