The course of the HOFMANN degradation in the 2-oxo-3-alkyl-9,10-dimethoxy-1,2,3,4,6,7-hexahydro-11bH-benzo[a]quinolizine series has been elucidated and the constitution of the degradation products established. They represent 1,2,3,4-tetrahydroisoquinoline derivatives obtained by ring opening between the nitrogen atom and the carbon atom 4. In addition, a new synthesis of substituted 2-oxo-9,10-dimethoxy-1
HOFMANN在2-氧代-3-烷基-9,10-二甲氧基-1,2,3,4,6,7-六氢-11b H-苯并[a]喹诺嗪系列中的降解过程已经阐明,并且确定降解产物的组成。它们代表通过在氮原子和碳原子4之间开环而获得的1,2,3,4-四氢异喹啉衍生物。此外,取代的2-oxo-9,10-dimethoxy-1,2,3,描述了4,6,7-六氢-11b H-苯并[a]喹啉嗪。
