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.
clear colourless to light yellow or slightly pink
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.
Very reactive Michael-acceptor; the α-methylene-γ-butyrolactone ring system exists in many natural products of biological interest
Allergen in the Liliaeeae family of plants to whieh speeies such as Tulip, Alstromeria, Erythronium dens canis and americanum belong.
ChEBI: A butan-4-olide having a methylene group at the 3-position.
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.
