摘    要:本文报道用环加成-芳构化串连反应制备多取代芳香族化合物的方法。将1-氯-2-卤-3-苯硒基-1,3-丁二烯(5)与丁炔二酸二甲酯进行Diels-Alder反应时,能直接生成多取代的芳香族化合物4-苯硒基-5-卤代邻苯二甲酸二甲酯(4)。若用2-卤素-3-苯硒基-1,3-丁二烯(1)与丁炔二酸二甲酯进行Diels-Alder反应,只得到正常的加成产物4-苯硒基-5-卤素-1,4-环己二烯-1,2-二甲酸二甲酯(3),需再用DDQ处理,才得到多取代芳香族化合物(4)。

关 键 词:多取代芳香族化合物  合成  DDQ脱氢  Diels-Alder反应  环加成-芳构化串连反应

Abstract:The synthesis of polysubstituted aromatic compounds by using tandem cycloaddition aromatization reaction was reported. 1 Chloro 2 halo 3 phenylseleno 1,3 butadiene (5) was reacted with dimethyl acetylenedicarboxylate, the dimethyl 4 phenylseleno 5 halo o phthalate (4) was afforded directly. In the case of 2 halo 3 phenylseleno 1,3 butadiene (1) with dimethyl acetylenedicarboxylate, the polysubstituted aromatic compound (4) was prepared via the Diels Alder reaction followed by DDQ dehydrogenation.
Keywords:Polysubstituted aromatic compound  Synthesis  DDQ dehydrogenation  Diels  Alder reaction  Tandem cycloaddition  aromatization reaction
