The regioselectivity also varies as a function of SAL scaffold structure, but to a lesser extent 70-99% α-3, with {RhIBF 4} catalysts generally affording higher regioselectivity. We find no strong correlation between regio- and enantioselectivity, however, there seems to be a loose correlation between enantioselectivity and conversion/yield under the conditions examined
