Naturally occurring beta-triketones, isoleptospermone [3, 5-hydroxy-4-(2-methyl-1-oxopentyl)-2,2,6, 6-tetramethyl-4-cyclohexene-1,3-dione) from Leptospermum scoparium] and papuanone [6, 5-hydroxy-4-(1-oxohexyl)-2,2,6, 6-tetramethyl-4-cyclohexene-1,3-dione from Corymbia dallachiana], have been synthesized. Full spectral data are reported for the first time. The 13C NMR spectra of 3, 6, and the other triketones flavesone (2), leptospermone (4), and grandiflorone (5) found in Myrtaceous plants are fully assigned.
天然存在的β-三酮，即来自帚石楠（Leptospermum scoparium）的异薄子木酮[3,5-二羟基-4-(2-甲基-1-氧代戊基)-2,2,6,6-四甲基-4-环己烯-1,3-二酮]和来自达拉奇桉（Corymbia dallachiana）的巴布亚酮[6,5-二羟基-4-(1-氧代己基)-2,2,6,6-四甲基-4-环己烯-1,3-二酮]已被合成。首次报道了完整的光谱数据。对桃金娘科植物中发现的3、6以及其他三酮黄酮（2）、薄子木酮（4）和大花酮（5）的¹³C NMR光谱进行了全归属。
