What is Tulipalin A?

Description

Tulipalin 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 properties

clear colourless to light yellow or slightly pink

The Uses of Tulipalin A

Very reactive Michael-acceptor; the α-methylene-γ-butyrolactone ring system exists in many natural products of biological interest

The Uses of Tulipalin A

Allergen in the Liliaeeae family of plants to whieh speeies such as Tulip, Alstromeria, Erythronium dens canis and americanum belong.

The Uses of Tulipalin A

α-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.

Definition

ChEBI: A butan-4-olide having a methylene group at the 3-position.

Contact allergens

Tulipalin 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.
