Aziridine-1-carboxylate ester alkene

Aziridine-2-carboxylic esters are preparecf from hexahydro-l,3,5-triazines with alkyl diazoacetates in the presence of SnCl,. A-Tosylmethylanilines apparently also undergo ionization to generate iminium species that are interceptable by alkenes 1,2,3,4-Tetrahydroquinolines are formed. ... [Pg.338]

For the examples reported so lar, usually in the presence of die alkene the azomethine ylide is generated in situ by photochemical disrotatory ring-opening of the aziridine (254 nm) in dioxane yielding pyrrolidines. (Obviously, thermal conrotatoiy ring-opening of aziridines demands conditions, which oppose an efficient stereocontrol of the subsequent cycloaddition with a,P-unsaturated carboxylic ester derivatives.)... [Pg.127]

Intramolecular and intermolecular 1,3-dipolar cycloadditions of aziridine-2-car-boxylic esters with alkenes and alkynes have been investigated [131, 132]. Upon heating, aziridine-2-carboxylates undergo C-2-C-3 bond cleavage to form azome-... [Pg.100]
