Verhalten von 7-Methoxy-neopinondimethylacetal-methoperchlorat gegenüber Säure

摘要

Dependent on reaction conditions acidic hydrolysis of 7-methoxy-neopinone-dimethylacetal-methoperchlorate (1) yields Δ8(14)-7-oxo-metathebainone-methoperchlorate (9), 7-methoxy-7.8-dehydro-metathebainone-methoperchlorate (13 a) or 7-hydroxy-morphothebaine-methoperchlorate (14), resp
