Decicco CP, Song Y, Evans DA: Intramolecular O-arylation of phenols with phenylboronic acids: application to the synthesis of macrocyclic metalloproteinase inhibitors. Org Lett. 2001 Apr 5;3(7):1029-32. [reaction: see text]. The copper acetate mediated intramolecular O-arylation of phenols with phenylboronic acid pseudopeptides is the key step in the preparation of macrocyclic biphenyl ether hydroxamic acid inhibitors of collagenase 1 and gelatinases A and B. The intramolecular macrocyclization was found to be mild and tolerant of common chemical functionality. This methodology should provide a general route to macrocyclic biphenyl ethers. |
