A palladium-catalyzed domino transformation of gem-dibromoolefins leading to novel polycyclic benzo[c]carbazoles is described. A unique feature of the current reaction is the participation of both bromides in C–H functionalization processes. Mechanistic studies were conducted to ascertain the sequence of reaction events, and the results indicate that the (Z)-bromide likely reacts in preference to the
描述了钯-催化的宝石-二溴烯烃的多米诺转化,其导致了新型的多环苯并[ c ]咔唑。当前反应的一个独特特征是两种溴化物都参与了CH的H官能化过程。进行了机理研究以确定反应事件的顺序,结果表明(Z)-溴化物可能优先于(E)-溴化物反应。

condition (KOBut in refluxing toluene) has been studied. Interestingly, these propargyl systems with one arm attached with substituted 3-indolyl derivatives leaving the other arm unsubstituted produced the 3,4-furan fused dihydrocarbazole derivatives 6a-6g (and not the expected carbazole derivatives) as the predominant product (70–82%) making this methodology to access such derivatives an attractive route.

The present invention provides novel compounds of Formula (I) and Formula (II) and pharmaceutically acceptable salts, solvates, hydrates, tautomers, stereoisomers, isotopically labeled derivatives, and compositions thereof. Also provided are methods and kits involving the compounds or compositions for treating or preventing proliferative diseases (e.g., cancers (e.g., leukemia, melanoma, multiple myeloma), benign neoplasms, angiogenesis, inflammatory diseases, autoinflammatory diseases, and autoimmune diseases) in a subject. Treatment of a subject with a proliferative disease using a compound or composition of the invention may inhibit the aberrant activity of cyclin-dependent kinase 7 (CDK7), and therefore, induce cellular apoptosis and/or inhibit transcription in the subject.
