1R,9S α-Narcotine has been converted to 1S,9S β-narcotine by reaction with thiophosgene, followed by sodium acetate in acetic acid. Conversion to 1R,9R β-narcotine was achieved by sequential reaction of α-narcotine with α-chloroethyl chlorothionoformate, followed by aqueous sodium hydroxide. Finally, 1R,9R β-narcotine was converted to 1S,9R α-narcotine by reaction with thiophosgene, followed by sodium
1 - [R,9小号α-丁已被转换为1小号,9小号β-汀通过与二氯硫化碳反应,然后在乙酸乙酸钠。转换到1 - [R,9 - [R β-汀是通过α-汀与α氯代乙基chlorothionoformate的顺序反应,随后加入氢氧化钠水溶液来实现的。最后,1 - [R,9 - [R β-汀转化成1级小号,9 - [R α-汀通过与二氯硫化碳反应,然后在乙酸乙酸钠。
