(R)-(+)-Frontalin (1) and its antipode (1′) were synthesized from (R)-(+)-2-hydroxy-2-methylpentane-1,5-dioic acid 5→2 lactone (2) and its antipode (2′), respectively. This established the absolute configurations of both enantiomers of frontalin and afforded key materials to study the relationship between pheromone activity and chirality.
