Iridium‐Catalyzed Linear‐Selective sp3 C−H Alkylation of N‐Methylamides Using Alkenes Enabled by Diphosphite Ligands

Chemistry – A European Journal, EarlyView.
An iridium‐catalyzed linear‐selective sp3 C─H alkylation of N‐methylamides with alkenes is described. This method tolerates various N‐methylacetamide derivatives and has a broad alkene scope. Mechanistic studies were also conducted. Internal alkenes can also be used through in situ consecutive alkene isomerization.

(E)-2-(4-Nitrobenzylideneamino)benzamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
The title compound, C(14)H(11)N(3)O(3), adopts an E conformation, with a dihedral angle of 41.8 (1) ° between the mean planes of the two benzene rings. One of the amino H atoms forms an intra-molecular hydrogen bond with the amide N atom, while the other H atom forms an inter-molecular hydrogen bond with the carbonyl O atom of an adjacent mol-ecule ...

A fluorinated quinuclidine benzamide named LMA 10203 acts as an agonist of insect nicotinic acetylcholine receptors [PDF]

, 2012
In the present study, we take advantage of the fact that cockroach dorsal unpaired median neurons express different nicotinic acetylcholine receptor subtypes to demonstrate that simple quinuclidine benzamides such as the 2-fluorinated benzamide LMA 10203,

N-[Morpholino(phenyl)methyl]benzamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
The title compound, C(18)H(20)N(2)O(2), crystallizes with two mol-ecules in the asymmetric unit. The morpholine rings of both mol-ecules adopt chair conformations. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds. One phenyl ring is disordered over two orientations in a 0.665 (5):0.335 (5) ratio.
