An unprecedented palladium-catalyzed picolinamide-directed coupling of C(sp2)–H and C(sp2)–H has been developed with exclusive formation of the six-membered ring heterocyclics – quinolinone and pyridone.

A chiral disulfonimide (DSI)‐catalyzedasymmetric reduction of N‐alkyl imines with Hantzsch esters as a hydrogen source in the presence of Boc2O has been developed. The reaction delivers Boc‐protectedN‐alkyl amines with excellent yields and enantioselectivity. The method tolerates a large variety of alkyl amines, thus illustrating potential for a general reductive cross‐coupling of ketones with diverse
Fe(BF4)2·6H2O/2,6-pyridinedicarboxylic acid catalysed nitrosation of a wide variety of substituted styrenes has been developed in the presence of t-BuONO/NaBH4 under H2 pressure (10 bar) in MeOH–H2O (5 : 1) to afford corresponding oximes in good to excellent yields.
