Synthesis of methyl-substituted trans-fused tetrahydropyrans via 6-endo cyclization

A stereocontrolled synthesis of methyl-substituted trans-fused tetrahydropyrans having methyl groups adjacent to the ring oxygen is described. The strategy involves the coupling reaction of sulfonyl-stabilized oxiranyl anions with triflates and 6-endo cyc

Stereoselective synthesis of the 6,7,6- and 6,7,7-ring systems of polycyclic ethers by 6-endo cyclization and ring expansion

A new strategy for the stereoselective synthesis of the trans-fused seven-membered cyclic ethers corresponding to subunits of brevetoxin B and hemibrevetoxin B has been developed. The strategy involves alkylation of an oxiranyl anion and B-endo cyclization followed by one-carbon homologation of a tetrahydropyran to an oxepane using trimethylsilyldiazomethane.
