• Convergent Synthesis and Structural Confirmation of Phellodonin and Sarcodonin ε
  作者：Ippei Usui、David W. Lin、Takeshi Masuda、Phil S. Baran

  DOI：10.1021/ol400709f

  日期：2013.5.3

  The first synthesis of members of the sarcodonin family, phellodonin and sarcodonin epsilon, is reported herein. This verifies that the unprecedented and seemingly unstable N,N-dioxide-containing benzodioxazine framework can be constructed in the laboratory and lends further support to the proposed structures. The key step in the synthesis involves a biomimetic hetero-Diels-Alder reaction between a pyrazine N-oxide and an ortho-quinone.

  日期：2009.2.5

  Two sequential Suzuki coupling reactions have been developed for efficient synthesis of synthetically and biologically important 3,6-disubstituted 2,5-dioxybenzoquinone architectures in a highly chemoselective controlled manner. The method serves as a key step in the total synthesis of leucomelone in three steps and in 61% overall yield.

  Biologically and pharmaceutically relevant arylated quinones (Quin‐Ar) have been synthesized via direct CH arylation of a variety of phenols using arylboronic acids. An inexpensive, environmentally friendly iron catalyst, ferric sulphate, Fe2(SO4)3, was employed in this operationally simple and efficient method.

  Six pulvinic acids (pulvinic, pinastric, atromentic, xerocomic, isoxerocomic, variegatic) and a polyporic acid (atromentin) were synthesised. A set of terphenyl-quinones was prepared through sequential Suzuki-Miyaura couplings. Then, a rearrangement into pulvinic bis-lactones was induced by the action of Ac2O/DMSO. Ring openings and deprotections achieved total syntheses. Fluorescence properties of
