AbstractAcid-catalyzed recyclization of 4-acetoxy-9-furylnaphtho[2,3-b]furans efficiently produced naphtho[1,2-b:3,4-b’]difurans. On the other hand, 4-aminonaphtho[2,3-b]furans failed to undergo the analogous recyclization into benzo[g]furo[2,3-e]indoles. The difference in behavior of these two types of substrates was explained by employing density functional theory calculations. Graphical abstract
摘要4-乙酰氧基-9-呋喃基萘并[ 2,3- b ]呋喃的酸催化再循环有效地产生了萘并[1,2- b: 3,4- b' ]二呋喃。另一方面,4-氨基萘[2,3- b ]呋喃没有经历类似的环化成苯并[ g ]呋喃[2,3- e ]吲哚。通过使用密度泛函理论计算来解释这两种类型的基材在行为上的差异。 图形概要
