The synthesis is described of the epimeric 1-amino-1,2,3,14b-tetrahydro-4H-pyrido [1,2-d]dibenzo [b,f][1,4]oxazepines 2 and their N-substituted analogues. The cis-amines 33, 36 and 38 were prepared from the ketone 31 by reduction of the corresponding oxime whereas the trans isomers 12, 50 and 51 were prepared from the 1-ethoxycarbonyl derivative 44 by Curtius degradation. Attempts to convert the trans
描述了差向异构的1-氨基-1,2,3,14b-四氢-4 H-吡啶并[1,2- d ]二苯并[ b,f ] [1,4]氧杂ze庚因2及其N-取代基的合成。类似物。该顺式-胺33,36和38分别通过还原相应的肟,而从酮31制备反式异构体通过库尔提斯降解从1-乙氧衍生物44制备12,50和51。尝试通过与叠氮化钠的S N 2置换反应将反式醇7转化为差向型叠氮基化合物,导致重排,从而得到新的环系统14-叠氮基-11-甲氧基-1,2,14,14a-四氢- 4小时-pyrrolo [1,2- d ]二苯并[ b,g ] [1,4]恶唑啉24代替标题化合物。
