The original racemic patents described the use of resolution to give a chiral oxirane, such as 25, as an intermediate or the use of a chiral auxiliary (20) to produce the salmeterol enantiomers. Alkylation of chiral amine 20 with 2-benzyloxy-5-(2-bromo-acetyl)-benzoic acid methyl ester, followed by diastereoselective reduction of the ketone with lithium borohydride furnished intermediate 21 after chromatographic separation of the diasteromers. Removal of the benzyl group and the chiral auxiliary was...
