This invention concerns 2,3,5,6-dibenzobicyclo[5.1.0]octanes which may be substituted at the 4-position by either halogen, ketonic oxygen or hydroxyl. These compounds are prepared from 5H-dibenzo[a,d]cyclohepten-5-one by reaction with ethyl trichloroacetate in the presence of sodium methoxide to give 8,8-dichloro-2,3,5,6-dibenzobicyclo[5.1.0]octan-4-one which is reduced to the corresponding 4-hydroxy compound. The resulting 4-hydroxy compound is dehalogenated and converted to the corresponding 4-chloro or 4-keto compound. The 4-substituted compounds are useful in preparing other compounds of our invention. 4-Dialkylaminopropylidenedibenzobicyclo[5.1.0]octane compounds and 4-dialkylaminopropyldibenzobicyclo[5.1.0]octane compounds, useful as antidepressant agents, are prepared from, respectively, dibenzobicyclo[5.1.0]octan-4-one by reaction with a dialkylaminopropyl Grignard reagent followed by dehydration of the resulting carbinol or by reaction of a 4-halo-2,3,5,6-dibenzobicyclo[5.1.0]octane with a dialkylaminopropyl Grignard reagent. Both the dialkylaminopropyl and the dialkylaminopropylidene compounds are converted to the corresponding monoalkylamino compounds by dealkylation.
这项发明涉及2,3,5,6-二苯并[5.1.0]辛烷,可以在4位被卤素、酮氧或羟基取代。这些化合物是从5H-二苯并[a,d]环庚烯-5-酮与三氯乙酸乙酯在甲氧基钠存在下反应制备而成,得到8,8-二氯-2,3,5,6-二苯并[5.1.0]辛烷-4-酮,然后还原为相应的4-羟基化合物。所得的4-羟基化合物脱卤并转化为相应的4-氯或4-酮化合物。这些4-取代化合物在制备我们的其他化合物时非常有用。4-二烷基氨基丙烯基二苯并[5.1.0]辛烷化合物和4-二烷基氨基丙基二苯并[5.1.0]辛烷化合物,作为抗抑郁剂,分别由二苯并[5.1.0]辛烷-4-酮与二烷基氨基丙基格氏试剂反应后脱水得到的碳醇,或者由4-卤代-2,3,5,6-二苯并[5.1.0]辛烷与二烷基氨基丙基格氏试剂反应得到。二烷基氨基丙基和二烷基氨基丙烯基化合物均通过去烷基化转化为相应的单烷基氨基化合物。
