A one‐dimensional version of the heteronuclear multiple bond correlation experiment (HMBC) is shown to be an excellent alternative to the full two‐dimensional experiment when the carbon resonances are well resolved. The quaternary resonances of lambertellin, a metabolite of Ciboria gordonii Funk, are correlated to the previously assigned proton resonances by selective transfer of zero and double quantum coherence to observable proton magnetization by a frequency‐selective carbon decoupler pulse.
