α-Carboline-1-oxide(I)与乙酸酐得到2-乙酰氧基-9-乙酰基-α-咔啉;用硫酸二甲酯得到盐(Ⅱ; R = H)。后者的盐通过碱转化为an鎓碱(III; R = OMe)。盐(Ⅱ; R = H)和碱(Ⅲ; R = OMe)通过足够碱性的亲核试剂转化为2-取代的α-咔啉;盐(II; R = Me)与碱性亲核化合物反应更容易。

salt is converted by alkali into the anhydronium base (III; R = OMe). The salt (II; R = H) and the base (III; R = OMe) are converted by sufficiently basic nucleophilic reagents into 2-substituted α-carbolines; the salt (II; R = Me) reacts even more readily with basic nucleophilic compounds.
