摘要：

Oligo(tetrahydrofurans) (oligo-THFs) 8-12 have been synthesised stereoselectively. Multiple Williamson reactions were used as key steps. While oligo-TWFs with an even number of THF rings like the bi-THFs 8 and 9 as well as the tetra-THFs 10 and 11 were obtained by a bidirectional strategy, the penta-THF 12 with an odd number of THF rings was prepared by a convergent strategy with a sulfone-aldehyde coupling as connecting step, The oligo-THF products are important structural features of natural (Annonaceae acetogenins) and non-natural (artificial inn channels) products.
