Regio- and stereoselective ring opening of epoxides. Enantioselective synthesis of 2,3,4-trisubstituted five-membered heterocycles
摘要:
By using the appropriate protecting groups. the opening of (2S.3S.4E)-5-benzenesulfonyl-2.3-epoxy-pent-4-en-1-ol (-)-2 could be controlled and used for the synthesis of the enantiomeric pyrrolidines (+)- and (-)-18 and the tetrahydrofuran analogs (+)- and (-)-19.

[reaction: see text] Several chiral buildingblocks have been obtained easily in large quantities from an epoxysulfone (9) that could be obtained in both enantiomeric forms from accessible starting materials.
