title: Rhodium-catalyzed enantioselective 1,6-addition of arylboronic acids to enynamides: asymmetric synthesis of axially chiral allenylsilanes.
abstract: Rhodium-catalyzed asymmetric 1,6-addition of arylboronic acids to β-alkynyl acrylamides substituted with a silyl group on the alkyne terminus took place to give high yields of axially chiral allenylsilanes with 94-99% enantioselectivity, which was realized by use of a rhodium/chiral diene complex.
