“…[59] Moreover, methods were developed which, for compounds with 13 C in its natural abundance, allow the determination of 13 CÀ 13 C coupling constants, [60] which in turn give information on the conformation of a molecular backbone. Armed in this manner, we tackled the conformation analysis of the intermediate 22, [57] which lies on the synthetic pathway of 21, the largest such compound amenable to such an analysis (Scheme 11). The result [61] was a complete surprise for us: There was none or only a low, local conformational preference in the segments A and C. The high conformational preference hoped for in the tt conformation was, however, found in the segments B and D.…”

“…[59] Zum anderen wurde ein Verfahren entwickelt, mit dem bei natürlicher Isotopenhäufigkeit 13 C-13 C-Kopplungskonstanten bestimmt werden können, [60] die klare Aussagen über die Konformation eines Kohlenstoffgerüsts zulassen. So gerüstet, begaben wir uns an die Konformationsanalyse der gröûten für uns noch analysierbaren Zwischenstufe 22 aus der Synthese von 21 [57] (Schema 11).…”
