A stereoselective synthesis of tetrahydropyran-tetrahydrofuran (THP-THF) core 2 of (+)-muconin (1) has been achieved using Prins cyclization as a key step to construct tetrahydropyran moiety. Other important transformations such as Wittig olefination, Sharpless epoxidation, regio-, and stereoselective exo-cyclization of the epoxy alcohol, titanocene induced regioselective deoxygenation of 2,3-epoxy alcohol, Grignard reaction, and Barton-McCombie reaction are successfully employed to accomplish the synthesis of THP-THF core 2.

"Chemical Equation Presented" A new strategy to access highly enantioenriched cyclic compounds (up to 98%) Is proposed using ω-ethylenic allylic substrates through a one-pot asymmetric allylic alkylation and ring-closing metathesis. Such starting compounds can be seen as synthetic equivalents of cyclic allylic substrates.
