Description and Uses

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.

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.
