Description

The title compound, C20H28O3, known as 'trichodermaerin' [systematic name: (4E)-4,9,15,16,16-penta-methyl-6-oxa-tetra-cyclo-[10.3.1.0(1,10).0(5,9)]hexa-dec-4-ene-7,13-dione], is a diterpene lactone which was isolated from Trichoderma asperellum. The structure has a tetra-cycic 6-5-7-5 ring system, with the cyclo-hexa-none ring adopting a twisted half-chair conformation and the cyclo-pentane ring adopting a half-chair conformation, whereas the cyclo-heptene and tetra-hydro-furan-anone rings are in chair and envelope (with the methyl-substituted C atom as the flap) conformations, respectively. The three-dimensional architecture is stabilized by C-H⋯O inter-actions.

Translated Description (Arabic)

المركب الرئيسي، C20H28O3، المعروف باسم "trichodermaerin" [الاسم المنهجي: (4E) -4،9،15،16،16 - penta - methyl -6 - oxa - tetra - cyclo - [10.3.1.0(1،10).0(5،9)] hexa - dec -4 - ene -7،13 - dione]، هو ديتربين لاكتون تم عزله عن Trichoderma asperellum. يحتوي الهيكل على نظام حلقي رباعي الحلقات 6-5-7-5، حيث تتبنى الحلقة الحلقية سداسية لا شيء تشكيلًا نصف كرسيًا ملتويًا وتتبنى الحلقة الحلقية بنتان تشكيلًا نصف كرسي، في حين أن الحلقات الحلقية هبتين ورباعية هيدرو فيوران أنون موجودة في الكرسي والمغلف (مع ذرة C المستبدلة بالميثيل كرفرف)، على التوالي. يتم تثبيت البنية ثلاثية الأبعاد من خلال تفاعلات C- H - O.

Translated Description (French)

Le composé du titre, C20H28O3, connu sous le nom de « trichodermaérine » [nom systématique : (4E) -4,9,15,16,16-penta-méthyl-6-oxa-tétra-cyclo- [10.3.1.0(1,10).0(5,9)] hexa-déc-4-ène-7,13-dione], est une lactone diterpénique qui a été isolée de Trichoderma asperellum. La structure a un système cyclique tétracyclique 6-5-7-5, le cycle cyclo-hexa-none adoptant une conformation de demi-chaise torsadée et le cycle cyclo-pentane adoptant une conformation de demi-chaise, tandis que les cycles cyclo-heptène et tétra-hydro-furane-anone sont dans des conformations chaise et enveloppe (avec l'atome de C substitué par un méthyle comme volet), respectivement. L'architecture tridimensionnelle est stabilisée par des interactions C-H ‹ O.

Translated Description (Spanish)

El compuesto del título, C20H28O3, conocido como 'trichodermaerin' [nombre sistemático: (4E)-4,9,15,16,16-penta-metil-6-oxa-tetra-ciclo- [10.3.1.0(1,10).0(5,9)]hexa-dec-4-eno-7,13-diona], es una lactona diterpénica que se aisló de Trichoderma asperellum. La estructura tiene un sistema de anillo tetra-cíclico 6-5-7-5, con el anillo ciclo-hexano que adopta una conformación de media silla retorcida y el anillo ciclo-pentano que adopta una conformación de media silla, mientras que los anillos ciclo-hepteno y tetra-hidro-furan-anona están en conformaciones de silla y envoltura (con el átomo de C sustituido con metilo como aleta), respectivamente. La arquitectura tridimensional se estabiliza mediante interacciones C-H-O.
