Descripción

Application

• Preparation of single-enantiomer 2-methyl-4-heptanol, a pheromone of Metamasius hemipterus, using (S)-2-methoxy-2-(1-naphthyl)propionic acid.: This research outlines the synthesis of a single-enantiomer pheromone compound using (S)-2-methoxy-2-(1-naphthyl)propionic acid. The process highlights the importance of enantiopure intermediates like (−)-Methyl (R)-3-hydroxyvalerate in the synthesis of biologically active compounds (Ichikawa and Ono, 2006).

Other Notes

Chiral building block for EPC syntheses; selective anti-alkylation of its dianion; OH protection and reduction of ester group to aldehyde or alcohol functions; stereoselective preparation of a dioxanone with pivalaldehyde
