Abstract 4-Aroyl-1,2-dihydrobenzo[d]azepines, as well as their phenanthro[1,2-d]azepine keto analogs, under the action of formaldehyde in the presence of acid-base catalysts, can undergo diastereoselective transformation into spirocyclic systems, containing two spiro-fused hetero rings – tetrahydroazepine and bifunctionalized tetrahydrofuran. This transformation is provided by a combination of azepine-azepine
摘要 4-芳酰基-1,2-二氢-苯并[ d ]吖庚因,以及它们的菲并[1,2- d ]吖庚因酮类似物,甲醛在酸-碱催化剂的存在下的作用下,可以进行非对映选择性转化为螺环系统,包含两个螺环稠合的杂环——四氢氮杂和双功能化四氢呋喃。这种转化是通过底物的氮杂-氮杂再环化和其产物的螺环化的组合提供的。
