摘要: Abstract Reaction of arylboron reagents, arylboronic acids or arylborates, which are readily accessible by lithiation aryl bromides followed treatment with trimethoxyborane, α,β-unsaturated esters in the presence rhodium/( S )-binap catalyst proceeded high enantioselectivity to give yields optically active β-aryl up 98% ee. The depends on steric bulkiness ester moiety.
