| Description | Entilin B belongs to the class of organic compounds known as furopyrans. These are organic polycyclic compounds containing a furan ring fused to a pyran ring. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Pyran a six-membered heterocyclic, non-aromatic ring, made up of five carbon atoms and one oxygen atom and containing two double bonds. (1r,2s,3s,4r,8r,10s,12r,13r,15r,17r)-13-(furan-3-yl)-4,10-dihydroxy-15-isopropyl-5,7,7,12-tetramethyl-9,14,19,20-tetraoxahexacyclo[8.7.1.1¹,⁴.1²,¹⁵.0³,⁸.0¹²,¹⁷]icos-5-en-3-yl acetate is found in Entandrophragma utile. (1r,2s,3s,4r,8r,10s,12r,13r,15r,17r)-13-(furan-3-yl)-4,10-dihydroxy-15-isopropyl-5,7,7,12-tetramethyl-9,14,19,20-tetraoxahexacyclo[8.7.1.1¹,⁴.1²,¹⁵.0³,⁸.0¹²,¹⁷]icos-5-en-3-yl acetate was first documented in 2018 (PMID: 28987553).
