Common Name

methyl (1s,11s,12r,17r,18e)-18-ethylidene-12-hydroxy-8,14-diazapentacyclo[9.5.2.0¹,⁹.0²,⁷.0¹⁴,¹⁷]octadeca-2,4,6,9-tetraene-10-carboxylate

Description

Methyl (1S,11S,12R,17R,18E)-18-ethylidene-12-hydroxy-8,14-diazapentacyclo[9.5.2.0¹,⁹.0²,⁷.0¹⁴,¹⁷]Octadeca-2,4,6,9-tetraene-10-carboxylate belongs to the class of organic compounds known as strychnos alkaloids. These are alkaloids having a core structure based on the strychnan, stemmadenine (seco-curan), or the akuammicine (curan) skeleton. methyl (1s,11s,12r,17r,18e)-18-ethylidene-12-hydroxy-8,14-diazapentacyclo[9.5.2.0¹,⁹.0²,⁷.0¹⁴,¹⁷]octadeca-2,4,6,9-tetraene-10-carboxylate is found in Kopsia singapurensis. Based on a literature review very few articles have been published on methyl (1S,11S,12R,17R,18E)-18-ethylidene-12-hydroxy-8,14-diazapentacyclo[9.5.2.0¹,⁹.0²,⁷.0¹⁴,¹⁷]Octadeca-2,4,6,9-tetraene-10-carboxylate.
