Description

13,15-Dimethyl (1S,2R,6R,14S,15R,16R,18S,20S)-15-hydroxy-20-methoxy-17-oxa-3,13-diazaheptacyclo[12.6.2.0¹,¹⁶.0²,⁶.0³,¹⁸.0⁶,¹⁴.0⁷,¹²]Docosa-7,9,11-triene-13,15-dicarboxylate belongs to the class of organic compounds known as aspidofractine alkaloids. These are alkaloids with a structure that is based on the hexacyclic aspidofractine core. These compounds are related to the Aspidosperma group by formation of a C-2 to C-18 bond. (-)-Singapurensine B is found in Kopsia singapurensis. Based on a literature review very few articles have been published on 13,15-dimethyl (1S,2R,6R,14S,15R,16R,18S,20S)-15-hydroxy-20-methoxy-17-oxa-3,13-diazaheptacyclo[12.6.2.0¹,¹⁶.0²,⁶.0³,¹⁸.0⁶,¹⁴.0⁷,¹²]Docosa-7,9,11-triene-13,15-dicarboxylate.
