  Sex Pheromone of the Pine Sawfly, Macrodiprion nemoralis. Stereoselective Synthesis of the Sixteen Stereoisomers of 3,7,9-Trimethyl-2-tridecyl Acetate.

  摘要：

  The sixteen stereoisomers of 3,7,9-trimethyl-2-tridecyl acetate (5Ac) were prepared individually, each in over 99.5% stereochemical purity. The syntheses were based on the ring opening of a pure enantiomer of cis-3,4-dimethyl-gamma-butyrolactone using a pure stereoisomer of 1-lithio-2,4-dimethyloctane, the two stereogenic centres of which were introduced with high selectivity by alkylations of the amide enolates from the appropriate enantiomers of pseudoephedrine. (2S,3R,7R,9S)-3,7,9-Trimethyl-2-tridecyl acetate (SRRS-5Ac) has recently been found to be the major component of the female sex pheromone of Macrodiprion nemoralis (Hymenoptera: Diprionidae). A synthetic method for the preparation of a sixteen isomer mixture of 5Ac is also presented. This mixture has been found to be biologically active in field tests.

  日期：2019.2.1

  The total synthesis of majusculamide D (MJS-D) is described, a lipopentapeptide originally isolated from Lyngbya majuscula and reisolated from a Moorea sp. MJS-D possesses selective and potent cancer cell toxicity. A scalable and convergent strategy with a minimal number of purifications produced significant quantities of MJM-D for in vivo evaluations. The absolute configuration of the 1,3-dimethyl-octanamide

  描述了Majusculamide D（MJS-D）的总合成，一种脂五肽最初从Lyngbya majuscula分离出来，然后从Moorea sp。中分离出来。MJS-D具有选择性和有效的癌细胞毒性。具有最少纯化次数的可扩展且收敛的策略可产生大量MJM-D用于体内评估。通过经由ZACA化学合成该片段来确定1，3-二甲基-辛酰胺基序的绝对构型。

  alkylation strategies such as enolate reactivity as well as costs and problems associated with the chiral auxiliary. Practicability of this new method is demonstrated through application in natural product syntheses. Thus, an efficient synthesis of the northern part of the angiogenesis inhibitor borrelidin (28), the deoxypropionate building block 27, could be devised, representing a formal total synthesis

  提出了一种灵活制备任何低聚脱氧丙酸酯立体异构体的新的迭代策略，该策略依赖于对映体纯的格氏试剂的邻-DPPB-定向的铜介导的烯丙基取代。该反应在反应选择性的所有方面都得到了完美的控制。与已建立的烯醇盐烷基化方法相比，这一关键的CC键形成步骤具有相反的极性。因此，它避免了烯醇盐烷基化策略的现有问题，例如烯醇盐反应性以及与手性助剂相关的成本和问题。通过在天然产物合成中的应用证明了这种新方法的实用性。因此，可以设计出一种有效的血管生成抑制剂硼瑞林（28）北部的合成方法，即脱氧丙酸酯结构单元27，
