Материал из Онлайн справочника
Chelidonic acid is a heterocyclic organic acid with a pyran skeleton.
Preparation
Chelidonic acid can be prepared in two steps from diethyl oxalate and acetone:[1][2]
Uses
Chelidonic acid is used to synthesize 4-pyrone via thermal decarboxylation.[3]
Natural occurrence
Chelidonic acid was first discovered in extracts of Chelidonium majus.[4][5][6] It occurs naturally in plants of the Asparagales order.[7] Potassium chelidonate has been found to be responsible for nyctinasty in some plants; specifically, it has been found to regulate the closing of leaves of Cassia mimosoides at nightfall.[8][9]
