A simple convergent method for the construction of fused tri- and tetracyclic ethers

Starting from monocyclic ethereal aldehyde and dithioacetal S-oxide segments, trans-fused tri- and tetracyclic ethers were synthesized in high yields in short steps involving acetal cyclization and reductive etherification reactions. This sequence could offer a simple convergent approach to the synthesis of natural trans-fused polycyclic ethers.
