trans -3,4- trans : 2,3- cis - and 2,3- trans -3,4- trans : 2,3- trans -configuration based on (−)-epicatechin or (+)-catechin as constituent units, and their associated biflavanoid homologues, predominate in the heartwood of Acacia luederitzii . They are accompanied by stereochemical and functional analogues and by their putative flavan-3,4-diol and flavan-3-ol precursors.
摘要 [4,6]- 和 [4,8]-Proguibourtinidin 羧酸 (3,7,4'-三羟基官能团) 的 2,3-反-3,4-反: 2,3-顺-和 2, 3-反式-3,4-反式:基于(-)-表儿茶素或(+)-儿茶素作为组成单元的2,3-反式构型,以及它们相关的双黄酮同系物,在Acacia luederitzii的心材中占主导地位。它们伴随着立体化学和功能类似物以及它们推定的 flavan-3,4-diol 和 flavan-3-ol 前体。
