Two diastereoisomers of the C9 lactone, (3S, 5S, 6S) -3,5- dihydroxy- 6-methyl-δ-octanolide and (3S, 5S, 6S)-3,5-dihydroxy-6- methyl-δ- octanolide, have been enantioselectively synthesized and compared with the natural sample, thereby determining the absolute configuration of the methyl group in the acyl moiety of quillajasaponins to be S.
