The insecticidal tetrahydroisocoumarin, (3R,4S,4aR)-4,8-dihydroxy-3-methyl-3,4,4a,5-tetrahydro-1H-2-benzopyran-1-one, was synthesized as a racemate and as an optically active form using one-potesterification-Michael addition-aldol reaction of delta-hydroxy-alpha,beta-unsaturated aldehyde and diketene as a key step.
