An efficient convergent strategy for the construction of a trans-fused 6-6-6-6-membered tetracyclic ether ring system was developed. The key steps involve coupling of two cyclic ethers by esterification, SmI 2 -promoted intramolecular reductive cyclization of iodo ester to hemiacetal, dehydration to

The SmI 2 -induced reductive intramolecular cyclization of an aldehyde and b-alkoxy acrylate was further investigated for the synthesis of polycyclic ethers having an angular methyl group. The cyclization produced 6,6-and 6,7-membered bicyclic ethers having a methyl group at C2 or C6 and C2 or C7 po

A highly efficient strategy for the iterative synthesis of a trans-fused polytetrahydropyran ring system was developed. The new iterative method involves SmI2-induced reductive intramolecular cyclization of an aldehyde and a [~-alkoxy acrylate as the key step, producing a 2,3-trans-tetrahydropyran r
