The preparation of a 1,2,3,4,4a,5,9,9a-octahydro-2,5-methanothieno[3,2-g]quinoline, which can be considered as a rigid thieno[3,2-f]morphan system due to an additional two-atoms bridge between the 3 and 9 positions of the morphan nucleus, is described. The synthetic route involved the acidic cyclization of a 3-(2-thenyl)-2-azabicyclo[2.2.2]oct-7-ene, obtained by the Diels-Alder reaction between 1,3
1,2,3,4,4a,5,9,9a-octahydro-2,5-methanothieno [3,2- g ] quinoline的制备,可以认为是刚性的thieno [3,2- f描述了吗啡系统,这是由于吗啡核的3和9位之间存在一个额外的两个原子桥所致。合成路线涉及通过1,3,4-三甲基-2-(-)的Diels-Alder反应获得的3-(2-乙烯基)-2-氮杂双环[2.2.2] oct-7-烯的酸性环化反应。 2-噻吩基)-1,2-二氢吡啶和丙烯酸乙酯。
