摘    要:以价廉易得的己二酸二甲酯为原料, 在甲醇钠的催化下, 通过Dieckmann缩合反应得到2-氧代环戊烷羧酸甲酯, 收率82.2%; 2-氧代环戊烷羧酸甲酯再与丙烯腈在40%(质量比)苄基三甲基氢氧化铵甲醇溶液存在下, 经Michael加成制得1-(2-氰乙基)-2-氧代环戊烷羧酸甲酯, 收率82.5%; 进一步酸性脱羧得到3-(2-氧代环戊基)丙腈, 收率84.0%; 将脱羧产物通入装有Ni-Cu/γ-Al2O3催化剂的固定床反应器中, 催化环合最终得到6,7-二氢-5H-1-氮茚, 反应总收率33.8%.

Abstract:Methyl 2-oxocyclopentanecarboxylate was obtained via Dieckmann condensation from dimethyl adipate in 82.2% yield. Then the condensation product was reacted with acrylonitrile, in the presence of Triton B giving methyl 1-(2-cyanoethyl)-2-oxocyclopentane-carboxylate in 82.5% yield. 3-(2-Oxocyclopentyl)- propanenitrile was synthesized from methyl 1-(2-cyanoethyl)-2-oxocyclopentane-carboxylate by hydrolysis which was converted to the target molecule, 6,7-dihydro-5H-1-pyrindine, directly by reductive cyclization and aromatization in one step in the presence of Ni-Cu/γ-Al2O3. The total yield was 33.8%.
