A novel and efficient iron-catalyzed cyclization of ketoxime carboxylates and N,N-dialkylanilines for the modular synthesis of diverse pyridines was developed. The reaction was initiated by Fe-catalyzed N-O bond cleavage of ketoxime carboxylates in the presence of tertiary anilines. The methylene carbon on N,N-dialkylanilines functioned as a source of one-carbon synthon in the reaction. The reaction used readily available starting materials, tolerated various functional groups, and afforded 2,4-disubstituted and 2,4,6-trisubstituted pyridines in good to high yields under mild conditions.

A facile and novel protocol for the allylic amination of internal alkynes with amines by using a polymer-supported triphenylphosphane-palladium complex [PS-TPP-Pd] as a highly active heterogeneous reusable catalyst was developed. The catalyst exhibited remarkable activity and is re-usable over five consecutive cycles. The protocol was applicable for a variety of hindered and functionalized aromatic/ aliphatic amines and afforded the desired allylic products in good to excellent yield.
Direct Reductive Amination of Aldehydes and Ketones Using Phenylsilane: Catalysis by Dibutyltin Dichloride
Apodaca, Richard,Xiao, Wei
, p. 1745 - 1748 (2007/10/03)
(matrix presented) A procedure for direct reductive amination of aldehydes and ketones was developed which uses phenylsilane as a stoichiometric reductant and dibutyltin dichloride as a catalyst. Suitable amines included anilines and dialkylamines but not monoalkylamines.
