Mechanistic studies on the catalytic cycle of rhodium-catalyzed asymmetric 1,4-addition of aryltitanate reagents to α,β-unsaturated ketones
Addition of lithium aryl(tetraisopropoxy)titanates [ArTi(OPr-i)(4)(–)Li(+)] to α,β-unsaturated ketones proceeded with high enantioselectivity (up to 99% ee) in the presence of an excess amount of chlorotrimethylsilane and a rhodium catalyst (3 mol % Rh), generated from [RhCl(C(2)H(4))(2)](2) and (S)...
