THE SYNTHESIS OF NATURALLY OCCURRING 4-ALKYL- AND 4-ALKENYL-γ-LACTONES USING THE ASYMMETRIC REDUCING AGENT B-3-PINANYL-9-BORABICYCLONONANE

4-Hydroxy-2-alkynoates of high enantiomeric purity, available from the reduction of the corresponding ketones with B-3-pinanyl-9-BBN, are converted to 4-substituted-γ-lactones found in beetle and deer pheromones.
