The synthesis of D,-clenbuterol (I) and D,-clenbuterol ( ) is described. D,-clenbuterol (I) was prepared from 4-amino-a-bromo-3,5-dichloroacetophenone by reaction with D,-tert-butylamine followed by reduction of the keto group with NaBH,. D,-clenbuterol (11) was prepared from 4-amino-cl-tert-butylam

Abstract
A general scheme for the synthesis of (S)โ6โmethoxyโ2โpropanoic acid (naproxen) deuterated on the naphthyl ring, methoxy group, or both, is described. The resulting labeled naproxen derivatives are useful probes for examining atypical kinetics displayed by cytochrome P450 2C9. Copyright ยฉ 2007 John Wiley & Sons, Ltd.
