yields by the Pd/Rh catalyzed carboannulation of bicyclic and tricyclic hydrazines with 2-iodobenzonitrile, 2-cyanophenylboronic acid and 2-formylphenylboronic acid. The reaction with 2-formylphenylboronic acid afforded 3,4-disubstituted cyclopentenes as minor product along with indanones under Rh catalyzed conditions, whereas indanols were obtained as the major product under Pd catalyzed conditions. The
通过Pd / Rh催化双环和三环肼与2-碘苄腈,2-氰基苯基硼酸和2-甲酰基苯基硼酸的碳环化反应,可以很容易地以良好的产率制备官能化的茚满酮。与2-甲酰基苯基硼酸的反应在Rh催化的条件下提供了3,4-二取代的环戊烯与茚满酮一起作为次要产物,而在Pd催化的条件下获得了作为主要产物的茚满醇。所获得的产物可以容易地合成加工成药学上重要的分子。
