Biologically relevant 1,5-diazacyclooctanes derived from polyamines and acrolein, inhibit Aβ40 peptide fibrillization and significantly suppress cell cytotoxicity. Formal [4+4] cycloaddition reaction of imines is thus involved in modulating oxidative stress processes associated with neural diseases.

Cyclic imines are lipophilic marine toxins that bioaccumulate in seafood. Their structure comprises a cyclic-imino moiety, responsible for acute neurotoxicity in mice. Cyclic imines have not been linked yet to human poisonings and are not regulated in Europe, although the European Food Safety Authority requires more data to perform a conclusive risk assessment for consumers. This work presents ...

Under solid-state conditions, manganese(iii) acetate-mediated radical reactions of 1,3-cyclohexanedione and 5,5-dimethyl-1,3-cyclohexanedione with in situ generated imines proceeded efficiently by mechanical milling at room temperature and good to excellent yields were achieved.

Aldehydes, ketones and imines were readily reduced by sodium borohydride, with the participation of a small amount of water, in good to excellent yields using PEG400 as catalyst in the absence of organic solvents.  2005 Society of Chemical Industry

A general and efficient hydrosilylation of imines catalysed by a well defined NHC-carbene cyclopentadienyl iron complex has been developed. Both aldimines and ketimines are converted to the corresponding amines under mild conditions, and under visible light activation.

An efficient, easy to perform, one-pot reaction cascade for the synthesis of 2,5-disubstituted pyrroles from p-toluenesulfonyl protected imines and 4-nitrobut-1-yne under a combination of base and gold(III) catalysis is reported.

An umpolung approach toward nitrone construction utilizing a phosphine-mediated addition of 1,2-dicarbonyls to nitroso compounds is reported. The reaction exhibits a high degree of chemoselectivity and provides direct access to isoxazolidines, imines, and trisubstituted alkenes.

An efficient, simple-to-perform, one-pot reaction cascade to 2-methylenepyrrolidines from p-toluenesulfonyl protected imines and propargylated malonates under a combination of base and copper(I) catalysis is reported.

Hydrogenation of the N-bound phenyl rings of amines, imines, and aziridine is achieved in the presence of H(2) and B(C(6)F(5))(3), affording the corresponding N-cyclohexylammonium hydridoborate salts.

pure azo schiff bases were readily and conveniently accessible in high yields by mixing of the reagents either as aqueous slurry, or by grinding at room temperature. this method, unlike a classical method, needs neither harsh conditions nor organic solvents. the satisfactory results were obtained with excellent yields, short reaction time, and operational simplicity in the experimental procedur...
