Synthesis of optically active methadones, LAAM and bufuralol by lipase-catalysed acylations
摘要:
(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.

A method of preparing optically active methadones comprises an enzymatic process for the resolution of 1-dialkyl-amino-2-propanol and conversion of the enantiomers to the optically active methadones in high enantiomeric purity.
