Select your group: Either a primary or tertiaryalkyl group can be selectively introduced onto the nitrogen atom of tosylamides in a ruthenium‐catalyzed reaction employing hydrosilanes through a judicious choice in the esters that serve as the alkylsource (see scheme; Ts= 4‐toluenesulfonyl). These N‐alkylation reactions are useful for construction of naturally occurring azacyclic skeletons.
