In a different strategy, the racemic intermediate aldehyde (IX) has been obtained as follows: Swern oxidation of the known racemic alcohol (I) yields aldehyde (II), which is further reductively aminated with methylamine to produce the secondary amine (III). Acylation of amine (III) with 3,5-dichlorobenzoyl chloride (IV) leads to amide (V). Subsequent desilylation of (V) with HF in acetonitrile provides alcohol (VI). The thioketal group of (VI) is then removed by treatment with HgClO4 and CaCO3, yielding ketone (VII). Treatment of (VII) with O-methyl hydroxylamine, followed by separation of the resultant E-/Z- mixture of isomers furnishes the desired O-methyl oxime (VIII). The primary alcohol function of (VIII) is then oxidized under Swern conditions to provide aldehyde (IX)
