TL;DR: In this paper, a simple procedure for converting oximes to rearranged secondary amines is described, based on the rearrangement of the secondary amine structure of the oximes.
58 citations
TL;DR: Some chiral acetals are cleaved by organoaluminum reagents and the products are formed diastereoselectively, and the removal of the chiral auxiliary affords optically active alcohols as discussed by the authors.

TL;DR: Beckmann rearrangement has been used for the regioselective synthesis of α-alkylated amines by treatment of a wide variety of oxime sulfonates with alkylaluminum reagents, followed by excess diisobutylaluminum hydride as discussed by the authors.
Abstract: New aspects of Beckmann rearrangement are described: (1) A new approach has been demonstrated for the regioselective synthesis of α-alkylated amines by treatment of a wide variety of oxime sulfonates with alkylaluminum reagents, followed by excess diisobutylaluminum hydride. Analogous reactions provide a new route to imino thioethers, imino selenoethers, and imino nitriles. These new processes provide a simple route to dl-pumiliotoxin C and other alkaloids in a highly stereoselective fashion. (2) Intramolecular cyclization initiated by Beckmann rearrangement provides new entry to a wide variety of heterocyclic derivatives. Utility of new methodologies is illustrated by the straightforward synthesis of muscone and muscopyridine.
