(+)-muricatacin and analogs have been synthesized without ambiguity about the absolute configuration at the C-4 and C-5 centres. The observed [alpha]D are reported as well as the results obtained for the cytotoxicity assay with KB and VERO cell lines.

Reduction of optically pure acyl-lactones (2) by L-Selectride affords monoprotected syn diols with high diastereoselectivity; the reaction was applied to the stereo- and enantio-specific synthesis of (+)-exobrevicomin.

A Ru-catalyzed isomerization of Achmatowicz derivatives that opens unexplored routes to diversify the biogenic furanic platform is reported. The mechanistic insights of this formally redox-neutral intramolecular process were studied computationally and by deuterium labeling. The transformation proved to be a robust synthetic tool to achieve the synthesis of bioderived-monomers and a series of 4-keto-δ-valerolactones
报道了 Achmatowicz 衍生物的 Ru 催化异构化,该异构化开辟了使生物源呋喃平台多样化的未开发途径。通过计算和氘标记研究了这种正式的氧化还原中性分子内过程的机理见解。该转化被证明是一种强大的合成工具,可实现生物衍生单体和一系列 4-酮基-δ-戊内酯的合成,进一步促进了合成乙酰基合成的灵活策略的发展。还描述了两种天然产物(即 ( S , S )-muricatacin 和 ( S , S )-L-因子)的简洁且无保护基团的不对称全合成。
