Description

16,18-Dimethyl 18-hydroxy-23-methoxy-11,13,20-trioxa-3,16-diazaoctacyclo[15.6.2.0¹,¹⁹.0²,⁶.0³,²¹.0⁶,¹⁷.0⁷,¹⁵.0¹⁰,¹⁴]Pentacosa-7(15),8,10(14)-triene-16,18-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. 16,18-dimethyl 18-hydroxy-23-methoxy-11,13,20-trioxa-3,16-diazaoctacyclo[15.6.2.0¹,¹⁹.0²,⁶.0³,²¹.0⁶,¹⁷.0⁷,¹⁵.0¹⁰,¹⁴]pentacosa-7(15),8,10(14)-triene-16,18-dicarboxylate is found in Kopsia singapurensis. Based on a literature review very few articles have been published on 16,18-dimethyl 18-hydroxy-23-methoxy-11,13,20-trioxa-3,16-diazaoctacyclo[15.6.2.0¹,¹⁹.0²,⁶.0³,²¹.0⁶,¹⁷.0⁷,¹⁵.0¹⁰,¹⁴]Pentacosa-7(15),8,10(14)-triene-16,18-dicarboxylate.
