Abstract
Cyclic compounds are frequently found in natural products, prevailing specially in alkaloids. Whether the choice of nature for these carbonic skeletal frameworks, is conformationally beneficial, has yet to be explored. In this paper we try to show how nature’s choice of cyclic carbonic framework in two triquinane sesquiterpenes is responsible for populating specific conformers to provide bioactivity. Conformational analysis of cisoctahydropentalenes can provide a telltale sign that conformational preference may be a predesigned aspect of both (+)-epi goniofufrone and hirsutic acid. conformational analyses are done, using ωb97xd/6-311+G(d) level of theory. The model was then tested to analyze the stable conformers in, (+)-epi-goniofufrone and hirsutic acid, respectively. The results are in line with our previous findings on chondrosterin J, and further work is underway to find a comprehensive detailed conformational landscape for fused five membered rings.
