Anti and syn ketoxime ethers were reduced with a chiral reducing agent prepared from (−)-norephedrine and 2 eq of BH3 to give S and R amines respectively in up to 92% ee. The preferred absolute configuration of the amine was depended on the geometry of the oxime ether.

Going green! The rhodium(III)‐catalyzed annulation of arylketone O‐methyl oximes with isocyanates for the synthesis of 3‐methyleneisoindolin‐1‐ones is reported (see scheme). This reaction exhibits high regioselectivity, functional‐group tolerance, and broad substrate scope, without the use of additives or production of environmentally hazardous waste.
