Methylation of damnacanthal with diazomethane gave a methyl ketone derivative, while methylation with dimethyl sulfate and anhydrous potassium carbonate gave a monomethy ether and munjistin dimethyl ether (m.p. 263∼265°), and methylation with methyl iodide and silver oxide gave a trimethyl ether. The infrared absorption spectra of these methyl derivatives and other derivatives of damnacanthal were measured.
用重氮甲烷甲基化可得到甲基酮衍生物,用硫酸二甲酯和无水碳酸钾甲基化可得到一甲基醚和门冬酰胺二甲醚(m.p. 263∼265°),用甲基碘和氧化银甲基化可得到三甲基醚。测量了这些甲基衍生物和达玛坎塔醛其他衍生物的红外吸收光谱。
