  Synthesis of Luminacin D

  摘要：

  The total synthesis of luminacin D (1) is reported on the basis of two aldol reactions to form the carbohydrate sector, aldehyde 30. Reaction of aldehyde 30 with the aryllithium intermediate derived from aryl iodide 38, cleavage of the silyl ether, and oxidation led to keto aldehyde 41. This advanced intermediate could be converted to luminacin 1 and its 6', 8'-epimer.

  can be achieved by 1,3‐chelation‐controlled allylation of aldehydes that possess a non‐chelating α‐ether substituent, even if the α‐position is a quaternary centre and/or a spiro‐epoxide. This reaction was used as a key step in an enantioselective synthesis of the angiogenesis inhibitor luminacin D.

  通过具有非螯合α-醚取代基的醛的1,3-螯合控制的烯丙基化可以实现非常高的非对映选择性，即使α-位置为季中心和/或螺-环氧化物。该反应被用作血管生成抑制剂luminacin D的对映选择性合成中的关键步骤。
• Synthesis of Monoprotected 2-Alkylidene-1,3-propanediols by an Unusual SN2' Mitsunobu Reaction

  A simple and efficient route to monoprotected (E)- and (Z)-2-alkylidene-1,3-propanediols is described. The key step involves an unusual regio- and stereoselective S(N)2' Mitsunobu reaction of substituted 3-hydroxy-2-methylenealkanoates which are readily available from a Baylis-Hillman reaction between methyl acrylate and an aldehyde. These allylic alcohols, when treated with PPh(3), a carboxylic acid, and DEAD in THF at temperatures ranging from -40 degrees C to 22 degrees C, produced the corresponding 2-alkylidene-3-hydroxypropanoate derivatives (or (E)-2-(hydroxymethyl)-3-substituted-2-alkenoate derivatives) in >70% with S(N)2':S(N)2 ratio of 22:1 to >50:1. It was found that weak and bulky carboxylic acids and low temperatures favor S(N)2' addition. The reaction conditions were effective for alkyl substituted derivatives, but the addition of Et(3)N to the Mitsunobu conditions was necessary to improve the S(N)2':S(N)2 ratios for the vinyl 19 and phenyl 20 derivatives. The monoprotected (Z)- and (E)-2-alkylidene-1,3-propanediols can be efficiently synthesized by a three-step sequence involving either a transesterification, protection, and DIBAL-H reduction (>80% overall yield) or by the chemoselective reduction, protection, and ester cleavage (67% overall yield).
