coincide with those reported for the original isolation from bamboo (Phyllostachys edulis) leaves of the compound designated MCGA3. Comparison of the published spectroscopic data reported for MCGA3, with both reported literature values and spectroscopic data obtained from an authentic sample, leads to the conclusion that the compound isolated from bamboo (Phyllostachys edulis) leaves is instead methyl
描述了1- O-甲基绿原酸的第一次合成。这种化合物的短而有效的合成提供了实验室规模的材料以研究其生物学特性。合成包括将已知的(-)-4,5-环己叉基奎宁内酯进行C-1烷基化,然后将甲醇盐打开至羟基酯。将C-5羟基酰化,随后依次除去保护基,得到1- O-甲基绿原酸。该化合物的NMR光谱特征与最初从竹子(毛竹(Phyllostachys edulis))称为MCGA3的化合物的叶子。将报告的MCGA3光谱数据与已报道的文献数据和从真实样品中获得的光谱数据进行比较,得出的结论是,从竹叶(Phyllostachys edulis)叶中分离出的化合物是氯代甲烷。
