Absolute configuration of isovouacapenol C

Abstract

El compuesto del título, C27H34O5 {nombre sistemático: benzoato de (4aR,5R,6R,6aS,7R,11aS,11bR)-4a ,6-dihidroxi-4,4,7,11b-tetra-metil-1,2,3,4,4a,5,6,6a ,7,11,11a ,11b-dodeca-hidrofenantro [3,2-b]furan-5-ilo}, es un furano oditerpeno de casano, que se aisló de las raíces de Caesalpinia pulcherrima. Los tres anillos deciclohexano están transfusionados: dos de ellos están en conformaciones de silla con el tercero en una conformación de media silla retorcida, mientras que el anillo de furano es casi plano (desviación r.m.s. = 0.003 Å). Una interacción C-H-O intramolecular genera un anillo S(6). Las configuraciones absolutas de los centros estereogénicos en las posiciones 4a, 5, 6, 6a, 7, 11a y 11b son R, R, R, S, R, S y R, respectivamente. En el cristal, lasmoléculas están unidas en cadenas infinitas a lo largo de [010] por enlaces de hidrógeno O-H. También se producen contactos cortos C O [3.306 (2) -3.347 (2) Å] y lasinteracciones C—H.

Le composé du titre, C27H34O5 {nom systématique : (4aR,5R,6R,6aS,7R,11aS,11bR)-4a ,6-dihydroxy-4,4,7,11b-tétra ­ méthyl-1,2,3,4,4a ,5,6,6a ,7,11,11a ,11b-dodéca­hydro­phénanthro[3,2-b] furan-5-yl benzoate}, est un cassane furan­ oditerpène, qui a été isolé à partir des racines de Caesalpinia pulcherrima. Les trois anneaux cyclohexane sont trans-fusionnés : deux d'entre eux sont en conformation chaise avec le troisième en conformation demi-chaise torsadée, alors que l'anneau furane est presque planaire (déviation r.m.s. = 0,003 Å). Une actionintermoléculaire C—H O génère un cycle S(6). Les configurations absolues des centres stéréogéniques aux positions 4a, 5, 6, 6a, 7, 11a et 11b sont R, R, R, S, R, S et R, respectivement. Dans le cristal, lesmolécules sont reliées en chaînes infinies le long de [010] par des liaisons hydrogène O—H 0. Il se produit également des contacts courts et des interac ­tions CH π [3,306 (2) -3,347 (2) Å].

The title compound, C27H34O5 {systematic name: (4aR,5R,6R,6aS,7R,11aS,11bR)-4a,6-dihy­droxy-4,4,7,11b-tetra­methyl-1,2,3,4,4a,5,6,6a,7,11,11a,11b-dodeca­hydro­phenanthro[3,2-b]furan-5-yl benzoate}, is a cassane furan­oditerpene, which was isolated from the roots of Caesalpinia pulcherrima. The three cyclo­hexane rings are trans fused: two of these are in chair conformations with the third in a twisted half-chair conformation, whereas the furan ring is almost planar (r.m.s. deviation = 0.003 Å). An intra­molecular C—H⋯O inter­action generates an S(6) ring. The absolute configurations of the stereogenic centres at positions 4a, 5, 6, 6a, 7, 11a and 11b are R, R, R, S, R, S and R, respectively. In the crystal, mol­ecules are linked into infinite chains along [010] by O—H⋯O hydrogen bonds. C⋯O [3.306 (2)–3.347 (2) Å] short contacts and C—H⋯π inter­actions also occur.

المركب الرئيسي، C27H34O5 {الاسم المنهجي: (4aR، 5R، 6R، 6aS، 7R، 11aS، 11bR) -4a، 6 - dihy - droxy -4،4،7،11 b - tetra­methyl -1،2،3،4،4a، 5،6،6 a، 7،11،11 a، 11b - dodeca­ hydro­ phenanthro [3،2 - b] furan -5 - yl benzoate}، هو كاسان فوران - oditerpene، والذي تم عزله عن جذور Caesalpinia pulcherrima. يتم دمج الحلقات الحلقية الهكسانية الثلاث: اثنتان منها في تطابقات الكرسي مع الثالثة في شكل نصف كرسي ملتوي، في حين أن حلقة الفوران مستوية تقريبًا (انحراف الجذر التربيعي = 0.003 Å). ينتج عن التفاعل داخل الجزيئات C - H - O حلقة S(6). التكوينات المطلقة للمراكز التجسيمية في المواضع 4 أ و 5 و 6 و 6 أ و 7 و 11 أ و 11 ب هي R و R و R و S و R و S و R على التوالي. في البلورة، ترتبط الجزيئاتفي سلاسل لا حصر لها على طول [010] بواسطة روابط الهيدروجين O- H - O. C+O [3.306 (2)–3.347 (2) Å] تحدث أيضًا تلامسات قصيرة وتفاعلات C - H + π.
