Bryophyte Constituents; 7: New Synthesis of (+)-Rosmarinic Acid and Related Compounds

All articles of this category 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. bryophyte constituents - total synthesis - rosmarinic acid - allyl protective groups - chemoenzymatic resolution
