    • The sample used in this work has been prepared starting from 1-iodo-2-naphthol, 2-iodo-3-methoxyphenol and (R,R)-2,4-pentanediol, according to Scheme 1. The experimental procedure for the synthesis of 2-iodo-3-methoxyphenol has been improved by changing anisol into the corresponding methoxymethyl ether before the lithiation-iodination step. Despite the additional protection-deprotection steps, the new procedure affords a significantly higher total yield with respect to the previously published direct lithiation-iodination of anisol.
