α-sulfinyl carbanions as an efficient and general synthetic approach for the preparation of (−)-pentenomycin I (1) and (−)-epipentenomycin I (5) and their enantiomers (ent-1 and ent-5), starting from chiral (2S,5S,6S)-ester 6 and ent-6, respectively, has been demonstrated. Easy accesses to pentenomycin analogs have also been demonstrated through the Pummerer, Suzuki–Miyaura, and Sonogashira reactions.
α-亚磺酰基碳负离子分子内酰化反应的合成效用,是制备(-)-戊新霉素I(1)和(-)-表戊新霉素I(5)及其对映异构体(ent - 1和ent - 5),分别从手性(2 S,5 S,6 S)-酯6和ent - 6开始。通过Pummerer,Suzuki-Miyaura和Sonogashira反应也证明了易于获得戊喷霉素类似物。
