chemistry is reported. Both phenol and aromatic or aliphatic acid derivatives could be used under operator-friendly conditions (room temperature, technical solvents, under air). The discovery of the superiority of benziodoxolone-derived hypervalent iodine reagent 3d as an alkyne transfer reagent further expands the rapidly increasing utility of hypervalent iodine reagents in catalysis and is expected
A palladium-catalyzedintramolecular isoindolinone-forming aminooxygenation of alkenes with 1 atm of oxygen as oxidant is reported. A variety of functionalized alkenes and carboxylic acids can be used, and high yields were observed. Preliminary mechanistic studies revealed that the aminooxygenation products were formed through the oxidation of a C–PdII species using a strong oxidant, peroxide, which
报道了钯催化分子内异吲哚满酮形成的氨基氧合反应,其中氧原子为1个大气压。可以使用多种官能化的烯烃和羧酸,并且观察到高收率。初步的机理研究表明,氨基氧化产物是通过使用强氧化剂过氧化物将C-Pd II物种氧化而形成的,该过氧化物是由Pd(OAc)2 / bpy / O 2 / HOAc催化系统原位产生的。
Preparation of isoindolinones via a palladium-catalyzed diamination
A Pd(II)-catalyzed cyclization using oxidative olefin diamination was developed for the preparation of isoindolinones from ortho-olefinic N-methoxybenzamides. Using the optimized reaction conditions, the desired products were obtained in up to 90% yield using NFSI as the oxidant. This reaction provides an efficient and direct access to isoindolinones with amine functionality, an important drug skeleton
