Synthesis of some derivatives of the pyridazino[4,5-b][1,5]thiazepine ring system is reported. Thus, 5-benzyl-8-methyl-2-phenyl-2,3.4,5-tetrahydro-5H-pyridazino[4,5-b][1,5]thiazepin-9(8H)-one (5) was prepared by an intramolecular S-alkylation reaction, whereas the thiazepine ring of sulfone analogue 21, and that of the novel tricyclic pyrrolidino fused ring system 22 was elaborated by an intramolecular
报道了哒嗪并[4,5- b ] [1,5]噻氮平环系统的一些衍生物的合成。因此,5-苄基-8-甲基-2-苯基-2,3.4,5-四氢-5 H-哒嗪[4,5- b ] [1,5]噻嗪酮-9(8 H)-一(5)通过分子内的S-烷基化反应制备了环戊二烯,而通过分子内的C-烷基化反应制备了砜类似物21的硫氮平环和新型三环吡咯烷基稠合环系统22的噻唑烷环。还讨论了双环吡啶并噻嗪稠合的哒嗪系统的意外形成。
