Optical resolution of anti head-to-head coumarin dimer and determination of its absolute configuration based on CD spectral data

Article abstract of DOI:10.1016/S0040-4039(00)87874-0

(±)-anti Head-to-head coumarin dimer was successfully resolved into a pair of optically active forms in high yields, of which the absolute configuration was determined on the basis of CD and ¹H-NMR spectral data.
