Abstract:

The 3-substituted 3-hydroxybenzofuran-2-one unit is encountered in a large variety of natural pro-ducts with a wide spectrum of biological activities. Therefore, development of new methodologies to the construction of chiral quaternary center at the 3-position of benzofuran-2-one compounds were highly desired. A highly enantioselective Aldol reaction of benzofuran-2,3-ones with ketone catalyzed by N-(2-thiophenesulfonyl)prolinamide through enamine activation strategy was developed. As a result, a number of chiral 3-hydro-xyl substituted benzofuran-2-ones derivatives were synthesized with very good yields(up to 96%) and mode-rate to good enantioselectivities(up to 91% e.e.). This methodology substantially broadens the benzofuranone chemistry and offer functionalized chiral products.

Key words: Benzofuran-2, 3-one, Chiral carbon center, Asymmetric catalysis, Aldol reaction
