was transformed by initial treatment with methylmagnesiumbromide followed by oxidation of the corresponding alcohols with activated manganese dioxide into a series of ketones 15–17. Palladium(0) catalysed isomerization of the double bond in the prop-2′-enyl side-chain afforded ketones 36–38 which were subjected to the Corey–Bakshi–Shibata asymmetric reduction protocol to afford the R-3-alkoxy-1-(1′
