synthesis and characterization, including the stereochemistry, of a series of 3,4-dihydropyrromethenones and 2,3-dihydrodioxobilins are described. High-resolution /sup 1/H NMR spectral analysis allows the determination of the A ring coupling constants for a series of cis and trans model compounds. From these data and correlations, the relative stereochemistry in the A ring of phycocyanin and similar bile
描述了一系列 3,4-dihydropyrromethenones 和 2,3-dihydrodioxobilins 的合成和表征,包括立体化学。高分辨率 /sup 1/H NMR 光谱分析允许确定一系列顺式和反式模型化合物的 A 环耦合常数。根据这些数据和相关性,可以得出藻蓝蛋白 A 环中的相对立体化学和类似胆色素结构的结论。
