Tulipalin A Chemical Properties,Usage,Production

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

Uses

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

Uses

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

Uses

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.
