20-oxo-5,7,11,19-tetraoxapentacyclo[10.8.0.0²,¹⁰.0⁴,⁸.0¹³,¹⁸]icosa-1(12),2(10),3,8,13(18),14,16-heptaen-16-yl acetate

Description

20-Oxo-5,7,11,19-tetraoxapentacyclo[10.8.0.0²,¹⁰.0⁴,⁸.0¹³,¹⁸]Icosa-1(12),2,4(8),9,13(18),14,16-heptaen-16-yl acetate belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan. 20-oxo-5,7,11,19-tetraoxapentacyclo[10.8.0.0²,¹⁰.0⁴,⁸.0¹³,¹⁸]icosa-1(12),2(10),3,8,13(18),14,16-heptaen-16-yl acetate is found in Butea monosperma. 20-Oxo-5,7,11,19-tetraoxapentacyclo[10.8.0.0²,¹⁰.0⁴,⁸.0¹³,¹⁸]Icosa-1(12),2,4(8),9,13(18),14,16-heptaen-16-yl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan.
