An enantioselective copper-catalyzed intramolecular borylacylation is reported. The reaction proceeds through an initial enantioselective borylcupration of the styrene, followed by a nucleophilic attack on the tethered carbamoyl chloride. The products, chiral borylated 3,3-disubstituted oxindoles, were generated in excellent yields and enantioselectivities. The versatile carbon–boron bond provides a platform for a wide array of diversification.

A palladium-catalyzed direct addition of arylboronic acids to unprotected 2-aminobenzonitriles has been developed, leading to a wide range of 2-aminobenzophenones with moderate to excellent yields. The transformation has broad scope and high functional group tolerance. Moreover, 2-oxoindoline-7-carbonitrile and indole-7-carbonitrile were applicable to this process for the construction of 7-benzoyl-2-oxoindolines and 7-benzoylindoles, respectively. Among the compounds examined, compound 4e possessed the most potent anticancer activity against H446 and HGC-27 in vitro, with IC50 values of 0.02 μmol L-1 and 0.09 μmol L-1, respectively, while compound 4a showed the best potent anticancer activity against SGC-7901 with an IC50 value of 0.01 μmol L-1. Furthermore, we also performed in silico molecular docking calculations to investigate the interaction mode and binding affinity between the examined compounds and their tubulin target.

Palladium-catalyzed direct addition of 2-Aminobenzonitriles to sodium arylsulfinates: Synthesis of o-Aminobenzophenones

, p. 6439 - 6449 (2014/06/10)
The first example of the palladium-catalyzed synthesis of o-Aminobenzophenones in moderate to excellent yields via a direct addition of sodium arylsulfinates to unprotected 2-Aminobenzonitriles was reported. A plausible mechanism for the formation of o-Aminobenzophenones involving desulfination and addition reactions was proposed. The utility of this transformation was demonstrated by its compatibility with a wide range of functional groups. Thus, the method represents a convenient and practical strategy for synthesis of o-Aminobenzophenones.

Three series of pyrido-fused pyrimido[2,1-a]isoindol-7-ones were prepared from readily available (aminopyridinyl)(aryl)methanones by reduction followed by a Mitsunobu reaction with phthalimide and acid-catalysed cyclodehydration. This approach provides a wide variety of aza analogues of the antitumour agent batracylin.
