(R)- and (S)-Methadones and levo-alpha-acetylmethadol (LAAM) have been synthesised starting from lipase-catalysed acylation of dimethylaminopropan-2-ol. An approach to the synthesis of (R)-bufuralol is also presented. (C) 2003 Elsevier Science Ltd. All rights reserved.

An enantioselectivesynthesis of (R)-bufuralol via a ruthenium- and enzyme-catalyzed dynamickineticresolution (DKR) has been achieved. The synthesis starts from readily available 2-ethylphenol and provides (R)-bufuralol in high ee and a good overall yield of 31%.
