Abstract

Regioselective alkylation of phenol with cyclopentanol is achieved over Montmorillonite K10 clay, producing 2-cyclopentylphenol, the key intermediate. The synthesis of optically active ([])-penbutolol 1, an important antihypertensive drug, is realized in 5 steps from 2- cyclopentylphenol by employing Sharpless asymme
