Abstract

A short, practical synthesis of the bis-acetylenic natural product falcarinol 1 is reported. This method relies on the alternate functionalisation of bis-trimethylsilylbutadiyne 10. This may be achieved in one-pot, however, better yields were obtained more conventionally. Lipase mediated enzymatic kinetic resolution of the racemic adduct in an organic solvent afforded (+)-1 in 97% enantiomeric excess. The analogous process performed with racemic 3-acetoxy falcarinol 11 under aqueous conditions gave (-)-1. Oxidation of 1 with Dess–Martin periodinane gave falcarinone 2.
