Challenging the absence of observable hydrogens in the assignment of absolute configurations by NMR: application to chiral primary alcohols
Literature Information
Félix Freire, José Manuel Seco, Emilio Quiñoá, Ricardo Riguera
The absolute configuration of β-chiral primary alcohols devoid of observable hydrogens on one of the β-substituents at the asymmetric carbon (L1/L2) can be determined by comparison of the 1H NMR of their (R)- and (S)-9-AMA ester derivatives and analysis of the ΔδRS for the L substituent and the Cβ-H.
