Concise syntheses of the polyketide natural product (–)-muricatacin and (–)-( R , R )-L-factor (natural product enantiomer) were achieved in four steps by employing an organocatalytic asymmetric direct vinylogous aldol reaction of γ-crotonolactone and suitable aliphatic aldehydes as the key step.
聚酮化合物天然产物 (-)-muricatacin 和 (-)-( R , R )-L-因子(天然产物对映异构体)的简明合成是通过采用 γ-巴豆内酯和合适的脂肪醛作为关键步骤。

All of the four possible stereoisomers (ca. 95 % e.e.) of 5-hydroxy-4-decanolide (L-factors), the proposed autoregulator from , were synthesized from (±)-1-octen-3-ol in two or four steps employing the Sharpless asymmetric epoxidation as the keystep.
