New anthracene derivatives from Coussarea macrophylla

J Nat Prod. 2003 Jul;66(7):905-9. doi: 10.1021/np030066i.

Abstract

Five new naturally occurring anthracene derivatives, 1,4,10-trimethoxyanthracene-2-carbaldehyde (1), (1,4,10-trimethoxy-2-anthracen-2-yl)methanol (2), 1,4,8,10-tetramethoxyanthracene-2-carbaldehyde (3), 1,4,10-trimethoxyanthracene-2-carboxylic acid (4), and 1,3-dimethoxy-2-methoxymethylanthraquinone (5), were isolated from Coussarea macrophylla along with three known compounds, 3-hydroxy-1-methoxy-2-methoxymethylanthraquinone (6), scopoletin, and 3-epi-pomolic acid. The structures of 1-5 were determined on the basis of analysis of their spectroscopic data and by total synthesis.
