Acetylenecarboxylates

N-Unsubstituted pyrazoles and imidazoles add to unsaturated compounds in Michael reactions, for example acetylenecarboxylic esters and acrylonitrile readily form the expected addition products. Styrene oxide gives rise, for example, to 1-styrylimidazoles (76JCS(P1)545). Benzimidazole reacts with formaldehyde and secondary amines in the Mannich reaction to give 1-aminomethyl products. [Pg.54]

Acetylenic esters react well witli copper-zinc compounds. Propiolic esters are especially reacive [83], but otier acetylenecarboxylic acid derivabves suci as di-nietliyl acetylenedicarboxylate or propiolaniide 118 undergo biglily stereoselecive cis addition (Scienie 2.47) [46]. [Pg.66]

Additional information about the effect of amine structure and solvent on the steric course of the reaction of amines with acetylenecarboxylic esters has recently been reported by Huisgen [93]. [Pg.59]
