Prelaureatin, a new biogenetic key intermediate isolated from Laurencia nipponica
摘要:
A new monocyclic bromo ether, prelaureatin, proposed to be the key intermediate of bicyclic ethers, has been actually isolated from Laurencia nipponica and its structure is chemically established.
A bicyclic natural bromo ether, laureatin (7), and its monocyclic key intermediate, prelaureatin (6), have enzymatically been transformed from their original precursor, (3Z, 6S, 7S)-laurediol in single-step by lactoperoxidase.
