The (R)- and (S)-butanolides 7 and 9 are synthesized via asymmetric epoxidation from geraniol; the (R)-butanolide 7 is also obtained from (S)- citramalic acid. The butanolides 7 and 9 are valuable reference compounds for the determination of absolute stereochemistry in fungal and plant pre-anthraquinones.
