The impact of LR-HSQMBC very long-range heteronuclear correlation data on computer-assisted structure elucidation†
Abstract
The impact of LR-HSQMBC very long-range nJCH heteronuclear shift correlation data as a supplement to HMBC data as input for the computer-assisted structure elucidation program, Structure Elucidator®, is assessed for the first time. The severely proton-deficient xanthone antibiotic cervinomycin A2 and the alkaloid staurosporine were employed as a model compounds.
