A series of bicyclo analogues of several 2-phenylmorpholines were synthesized and tested for anti-tetrabenazine activity in mice. Most of the target compounds were prepared by reaction of 2-bromopropio-phenone (22) with the appropriate amino alcohol to form 2-phenylmorpholinols. Reduction of the 2-phenyl-morpholinols with sodium borohydride gave amino diols, which were cyclized to morpholines with
合成了几种2-苯基吗啉的一系列双环类似物,并在小鼠中测试了抗丁苯那嗪的活性。大多数目标化合物是通过2-溴丙苯酮(22)与适当的氨基醇反应生成2-苯基吗啉醇而制备的。用硼氢化钠还原2-苯基吗啉代醇得到氨基二醇,将其用酸环化成吗啉。或者,通过用2-溴乙醇烷基化苯基-(2-吡咯并)甲醇(32a)和苯基-(2-哌啶基)甲醇(32b),然后用酸环化所得的氨基二醇来合成恶嗪17和18。仅螺环化合物8和9具有与非环状化合物2a-3b相当的腹膜内抗丁苯那嗪活性,但口服给药途径中8和9的活性较弱。
