Stereoselective approach to trisubstituted tetrahydrofurans
摘要:
Functionalized allylsilanes 1 undergo with acetals 2 under mild Broensted acid catalysis a transacetalization-ring closure reaction to afford in fair to good yield and high diastereoselectivity all-cis-tetrahydrofurans 3. The stereochemical outcome is independent of the double bond geometry.
