FIVE INGOL ESTERS AND A 17-HYDROXYINGENOL ESTER FROM THE LATEX OF EUPHORBIA KAMERUNICA. ASSIGNMENT OF ESTERS USING 13C N.M.R. METHODS.

Article abstract of DOI:10.1016/0040-4039(84)80128-8

The structures of five ingol esters and a 17-hydroxyingenol ester from the latex of Euphorbia kamerunica have been determined.The ¹³C n.m.r. spectra of these compounds have been assigned using 2D δ_C/δ_H correlations.The specific positions of attachment of esters have been assigned unambiguously using ¹³C n.m.r. methods including 2D long range δ_C/δ_H correlations.
