Hetero Diels–Alderreaction of 3‐butyliminomethyl‐2‐aryl‐1H‐indoles (Schiff's base) 1 with p‐benzoquinone 2 affords six novel 5‐butyl‐11a‐aryl‐4a,5,11,11a‐tetrahydro‐11bH‐indolo[3,2‐c]quinoline‐1,4‐diones 3 in good yields. All the reactions proceeded with complete diastereoselectivity giving only one product in each case, which was characterized on the basis of its elemental analyses and spectral data
异狄尔斯–3-丁基亚氨基甲基-2-芳基-1 H-吲哚(席夫碱)1与对苯醌2的Alder反应制得六种新颖的5-丁基-11a-芳基-4a,5,11,11a-四氢-11b H-吲哚[3,2 - c ]喹啉-1,4-二酮3的收率很高。所有反应均以完全非对映选择性进行,在每种情况下仅给出一种产物,这是基于其元素分析和光谱数据(IR,1 H NMR和质量)表征的。
