✦ Synopsis

A one-dimensiooal 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 larnbertellin, 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 mag--netization by a frequency-selective carbon decoupler pulse.
