A robust and reliable method has been developed for reductive amination of primary amines with various aldehydes and ketones using Zn(ClO4) 2.6H20 as a catalyst. [In-H] generated in situ via a combination of InCl3 and Et3SiH is employed as an effective reducing system. A variety of secondary amines can be synthesized in a one-pot procedure in excellent yields.

The Beckmann rearrangement of oxime sulfonates with simultaneous nucleophilic trapping of the intermediary iminocarbocation by organoaluminum reagents is described.This process provides a new and highly efficient route to imino thioethers, imino selenoethers, imino nitriles, and α-alkylated amines starting from oxime sulfonates by the use of dialkylaluminum thiolates, selenolates, diethylaluminum chloride-trimethylsilyl cyanide, and trialkylaluminum-diisobutylaluminum hydride systems, respectively.The present organoaluminum-promoted Beckmann rearrangement of oxime sulfonates has been successfully applied to the synthesis of naturally occuring alkaloids, pumiliotoxin C and solenopsin A and B, in stereoselective fashion.Moreover, α,α-dialkylation of amines can be realized by the successive treatment of oxime sulfonates with trialkylaluminum followed by allylic or propargylic Grignard reagents in synthetically useful yields.
