A chemoselective N-arylation reaction of 2-aminopyridine derivatives with arynes in good to excellent yields has been described. The N-arylation products could be further applied to the facile construction of benzoisoquinuclidines and isoquinuclidines as
Mesoionic pyrido[1,2-a]pyrimidinones: A novel class of insecticides inhibiting nicotinic acetylcholine receptors
Zhang, Wenming,Holyoke, Caleb W.,Barry, James,Leighty, Robert M.,Cordova, Daniel,Vincent, Daniel R.,Hughes, Kenneth A.,Tong, My-Hanh T.,McCann, Stephen F.,Xu, Ming,Briddell, Twyla A.,Pahutski, Thomas F.,Lahm, George P.

A novel class of mesoionic pyrido[1,2-a]pyrimidinones has been discovered with exceptional insecticidal activity controlling a number of insect species, particularly hemiptera and lepidoptera. Mode-of-action studies showed that they act on nicotinic acetylcholine receptors (nAChRs) primarily as inhibitors. Here we report the discovery, evolution, and preparation of this class of chemistry. Our efforts in structure–activity relationship elucidation and biological activity evaluation are also presented.
METHOD FOR PRODUCING PEST CONTROLLING AGENT

Paragraph 0081, (2014/07/09)
To supply a derivative having a 2-acyliminopyridine structure and being represented by the following formula (I) in an amount required as a pest control agent stably and at a low cost, provided is a method comprising the steps of: acylating an amino group at position 2 of a compound represented by formula (A) by use of an acylating agent, to thereby produce a compound represented by formula (B); and further alkylating a nitrogen atom at position 1 of the compound represented by formula (B): [where Ar represents a phenyl group or a 5-to 6-membered heterocycle, R1 represents a C1-6 alkyl group, and Y represents a hydrogen atom; a halogen atom; a hydroxyl group; a C1-6 alkyl group which may be substituted with a halogen atom; a C1-6 alkyloxy group which may be substituted with a halogen atom; a cyano group; a formyl group; or a nitro group].

Unexpected formation of N,N-disubstituted formamidines from aromatic amines, formamides and trifluoroacetic anhydride
Mekhalfia, Abdelaziz,Mutter, Roger,Heal, William,Chen, Beining
, p. 5617 - 5625 (2007/10/03)
An intriguing selectivity towards the formation of the formamidine was observed upon the reaction of an amine with sodium hydride and trifluoroacetic anhydride in dimethyl formamide. Various aromatic amines were reacted with a series of N,N-disubstituted formamides as a solvent under the influence of trifluoroacetic anhydride to thoroughly probe this behaviour. A trend in selectivity is discussed and a proposed mechanism for the reaction is also presented.
