Ce. Hadden et al., Structural characterization of components of a mixture-characterization ofa facile oxidation product of cryptolepinone in situ, J HETERO CH, 36(2), 1999, pp. 525-531
The nmr analysis of a mixture of cryptolepinone and it's 5(N)-oxide in a 1.
5:1 ratio is discussed. The differentiation of the resonances of the two si
milar compounds, and elucidation of the unknown 5(N)-oxide relied primarily
on IDR-GHSQC-TOCSY data in conjunction with ROESY, GHSQC, and GHMBC experi
ments.
