Synthesis and Antitumor Evaluation of a Novel Class of 4-Substituted-1,4-Dihydroisoquinolin-3-ones
摘要:
An efficient method for the solution-phase parallel synthesis of 4-substituted-1,4-dihydroisoquinolin-3-ones is developed. The isoquinolinones were constructed employing an intramolecular Heck reaction, providing full regio- and stereoselectivity. Most of the synthesized compounds showed potent antiproliferative activities against tumor cell lines.

A palladium-catalyzed remote C–H silylation reaction has been developed through vinylic to aryl 1,4-palladium migration. By using alkyne-tethered aryliodides as the starting materials and hexamethyldisilane as the silylating reagent, the reaction involves cascade intramolecular carbopalladation, 1,4-palladium migration, and silylation with hexamethyldisilane, and leads to the formation of exocyclic
