| Summary: | 碩士 === 國立臺灣師範大學 === 化學系 === 102 === An efficient enantioselective conjugate addition of alkenylboronic acids to α,β-unsaturated carbonyl compounds was realized.
In the presence of 1 mol% of rhodium catalyst in situ prepared from [RhCl(C2H4)2]2 and ligand 25A, conjugation addition of various alkenylboronic acids to α,β-unsaturated carbonyl compounds furnishes the desired adducts in high yields (up to 99%) and in up to >99.5% ee.
