A catalytic protocol that reliably predicts and controls the site-selective incorporation of CO2 to a wide range of unsaturatedhydrocarbons utilizing water as formal hydride source is described. This platform unlocks an opportunity to catalytically repurpose three abundant, orthogonal feedstocks under mild conditions.
描述了一种催化协议,该协议利用水作为正式氢化物源可靠地预测和控制 CO2 的位点选择性掺入到各种不饱和烃中。该平台为在温和条件下催化重新利用三种丰富的正交原料提供了机会。

The total synthesis of the potent antifungal and antibiotic cyclic depsipeptide LI-F04a and its sidechain epimer was accomplished using macrolactonization to assemble the cyclic peptide core, followed by attachment of the 15-guanidino-3-hydroxypentadecanoyl (GHPD) sidechain. The sidechain was assembled by Yamaguchi−Hirao alkylation of both enantiomers of a chiral epoxide to provide a pair of enantiomeric
