Efficient and expeditious syntheses are described for rosmarinic acid (1) and its derivatives 2-4, making extensive use of allyl protective groups for both carboxylic acids and phenolic building blocks. (+)-(R)-Rosmarinic acid was obtained by a chemoenzymatic resolution of its phenyl lactic acid precursors.
The present invention provides a compound that inhibits the activity of TRPV4 and is useful for prevention or amelioration of an overactive bladder, an irritable bowel syndrome, etc. The compound is a rosmarinic acid derivative represented by the following formula (I) or a salt thereof:
