Total synthesis tetronasin (1), a tetronic acid polyether ionophore antibiotic, is reported in which the γ-unsubstituted α-acyltetronic acid structure is constructed by cyclization of a β-keto ester derivative 18 derived from tricyclic aldehyde intermediate 17 by reaction with methyl (diazoacetoxy)acetate in the presence of zirconium tetrachloride.
据报道,一种全合成的tetronasin(1),一种tetronic酸聚醚离子载体抗生素,其中γ-未取代的α-酰基tetronic酸结构是通过环化衍生自三环醛中间体17的β-酮酸酯衍生物18与甲基(在四氯化锆的存在下,加入重氮乙酰氧基)乙酸盐。
