Anodic oxidation of chiral sulfinylamines: a new route to highly diastereoselective α-alkylation of piperidine
摘要:
The anodic oxidation of some chiral non-racemic N-arylsulfinyl piperidines was investigated and for the first time alpha methoxylated sulfinyl piperidines were obtained. The so-formed compounds are equivalent of chiral N-sulfinyliminiums and used as new intermediates for the preparation of chiral alpha-substituted piperidine derivatives in good yield and diastereoselectivity.

Provided herein are aminoglycosides for the treatment of infections, and pharmaceutical compositions, methods, kits, and uses thereof. Also provided are a methods of making aminoglycosides that enables late-stage derivatization of the C6' and C3 " amino groups, thereby allowing facile access to previously inaccessible aminoglycosides.
