Abstract
Chiral [6R and 6S-(6α, 9α, 10α)]methano-1H-cyclooct[b]indol-9-ols were segregated into enantiomers through diastereomeric esters with (R)-α-trifluoromethylphenylacetic acid. The absolute configuration of the enantiomers was established by the NMR method using the shift reagent Eu(fod)3 and the circular dichroism spectra.
