The reactions of benzo[b]cyclohept[e][1,4]oxazine (9) with a 1.2 equivalent of α,ω-alkanediamines (2, n = 4—12) in ethanol at 80 °C afforded tropocoronands (5, n,n′ = 4,4—12,12) in a one-pot procedure and in high yields, while the reaction of 9 with an excess of 2 mainly gave tropopodands 12 (n,n′ = 4,4—6,6). The reactions of 9 with short-chain diamines 2 (n = 2,3) yielded bicyclic pyrazino or diazepino compounds as the main products. The reaction of 9 with ω-amino alcohol afforded the corresponding dihydroxy podands 23. The predicted pathways of the reaction of 9 with 2 were experimentally confirmed.
苯并[b]环庚烷并[e][1,4]恶嗪(9)与 1.2当量的α,ω-烷二胺(2,n = 4-12)在乙醇中于80 °C下进行反应,以一锅法和高产率得到了托硼烷(5,n,n′ = 4,4-12,12),而9与过量的2反应主要得到了托硼烷12(n,n′ = 4,4-6,6)。9 与短链二胺 2(n = 2,3)反应的主要产物是双环吡嗪或二氮杂卓化合物。9 与ω-氨基醇反应得到相应的二羟基荚膜 23。实验证实了 9 与 2 反应的预测途径。
