All four possible stereoisomers of lactone II isolated from
Streptomyces sp. Go 40/10, an autoregulator, have been efficiently
synthesized in a stereoselective manner starting from (S)-malic
acid and sorbic acid, and the absolute configuration was determined to be
2S, 3S, 9R, 10S.
以(S)-苹果酸和山梨酸为起始原料,以立体选择性方式高效合成了从自律调节链霉菌 Go 40/10 分离得到的内酯 II 的所有四种可能的立体异构体,并确定其绝对构型为 2S、3S、9R、10S。

Butalactin (1a) and lactone II (2a) have been synthesized starting from (S)-malic acid and sorbic acid by a straightforward route. The absolute stereochemistry of 1a and 2a was unambiguously established by this synthesis.
