| Hazard Information | Back Directory | [Uses]
Angelic Anhydride is a reagent in the improved synthesis of angelate esters, which are the active chemical behind the strong pain-relieving and spasmolytic action of extracts from the plant butterbur. | [Synthesis]
Angelic anhydride (dahuric anhydride) was prepared as follows: to a solution of angelic acid (5 g, 50 mmol) in dichloromethane (100 mL) at room temperature was added N,N’? Dicyclohexylcarbodiimide (8.6 mL, 60% in xylene, 25 mmol). The reaction mixtu |
