A dehydrogenation route to azomethine ylides and isoindoles
Journal of the Chemical Society, Perkin Transactions 1, 1989Dehydrogenation of methyl 1,2,3,4-tetrahydroisoquinolin-2-yl- and β-carbolin-9-yl-acetates with palladium black in dimethylformamide generates anti-azomethine ylides stereospecifically. The analogous reaction with methyl isoindolin-2-ylacetate gives the corresponding isoindole. Both types of product can be trapped by N-methylmaleimide. The mechanism of

Fused aziridines as sources of azomethine ylides
Chemistry of Heterocyclic Compounds, 2012The use of fused aziridines as sources of azomethine ylides in the synthesis of polyheterocyclic compounds is examined. Features of thermo- and photolytic opening of aziridines and aspects of the stereo-, regio-, and chemoselectivity of cycloaddition and electrocyclization of azomethine ylides are discussed.

Recent Advances in Azomethine Ylide Chemistry
1989Publisher Summary Azomethine ylides are planar molecules composed of one nitrogen and two terminal sp2 carbons. At most, four geometrical isomers are possible for these transient molecules. Their cycloadditions to olefin or acetylene dipolarophiles give rise to the formation of two sets of carbon-carbon bonds in a single step.

Azomethine, carbonyl and thiocarbonyl ylides
2002Abstract Simple addition of a carbene or carbenoid to a C-N double bond would be expected to result in the formation of an azomethine ylide. This is consistent with electrophilic attack of the carbene at the nitrogen atom lone pair. Formation of ylides in this manner was reviewed by Padwa and Hornbuckle in 1991.

1,3-Dipolar Cycloaddition Reactions of Porphyrins with Azomethine Ylides
The Journal of Organic Chemistry, 2005[reaction: see text] The behavior of porphyrins as dipolarophiles in 1,3-dipolar cycloadditions with azomethine ylides was studied. Depending on the nature of the substituent groups on the porphyrin macrocycles, the reaction can give monoadducts (chlorins) or bisadducts (isobacteriochlorins and bacteriochlorins). When a large excess of azomethine ylide
