The initial studies involving representative E and Z Substrates. Reactions performed under N2 atm. Conversion was determined by 19F NMR analysis of unpurified mixtures. Z:E by GC or 1H NMR spectra of unpurified mixtures (±2%). Enantioselectivity was determined by HPLC analysis of derived alcohols (±1%). Yield of purified products (±5%). See the Supporting Information for details. tpy = 2,6-bis(2-pyridyl)pyridine.
