Tulipalin A Usage And Synthesis
DescriptionTulipalin A is an unsubstituted -methylene-butyrolaetone eontained in the sap of tulips, Alstroemeria spp. (Peruvian lily) and Erythronium (dog tooth violet, fawn-lily). Tulipalin B seems to have a weak capacities to sensitize.
Chemical Propertiesclear colourless to light yellow or slightly pink
Usesα-Methylene-γ-butyrolactone (Tulipane) was used to develop optically active spiro-[butyrolactone-pyrrolidine] via Cu(I)-catalyzed exo-selective 1,3-dipolar cycloaddition of azomethine ylides.
UsesVery reactive Michael-acceptor; the α-methylene-γ-butyrolactone ring system exists in many natural products of biological interest
UsesAllergen in the Liliaeeae family of plants to whieh speeies such as Tulip, Alstromeria, Erythronium dens canis and americanum belong.
DefinitionChEBI: A butan-4-olide having a methylene group at the 3-position.
Contact allergensTulipalin A is the unsubstituted a-methylene-g-butyrolactone contained in the sap of damaged tulips (Liliaceae family) and Alstroemeria (Alstroemeriaceae family). Tulipalin B, due to hydrolysis of tuliposide B, seems to have a weak sensitizing capacity.
