An efficient and base-mediated one-pot regiospecificsynthesis of structurally diversified isoquinolines and benzo[h] isoquinolines from easily accessible ortho-formyl-arylketones and aryl/(het)arylmethanamines has been described. Challenging 3-alkynyl/alkenyl isoquinolines and bis-isoquinolines were easily attained through this developed chemistry, which can be further used for various organic transformations
已经描述了由容易获得的邻甲酰基-芳基酮和芳基/(杂)芳基甲胺有效和碱介导的一锅区域特异性合成结构上多样化的异喹啉和苯并[ h ]异喹啉。通过这种发达的化学方法很容易获得具有挑战性的3-炔基/烯基异喹啉和双异喹啉,它们可进一步用于各种有机转化。操作简便,高原子经济性,广泛的底物范围,官能团耐受性和对大规模合成的适用性是此开发方法的优势。
Palladium-Catalyzed Carbonylative Synthesis of Isoindolinones from Benzylamines with TFBen as the CO Source
A palladium-catalyzed C–H carbonylation of benzylamines for the synthesis of isoindolinone scaffolds has been developed. This protocol is conducted under gas-free conditions by using benzene-1,3,5-triyl triformate (TFBen) as a convenient CO surrogate, furnishing a variety of isoindolinone derivatives in moderate to high yields (up to 95%).
