title: SmI2-promoted intramolecular asymmetric pinacol-type ketone-tert-butanesulfinyl imine reductive coupling: stereoselectivity and mechanism.
abstract: The asymmetric ketone-tert-butanesulfinyl (t-BS) imine pinacol-type reductive coupling promoted by SmI(2) is described. Trans-1,2-vicinal amino alcohols were formed predominantly in excellent er and high dr. The stereochemical outcome provided evidence for a radical mechanism for SmI(2)-induced reductive couplings of t-BS imines.
