  Selective Activation/Coupling of Polyhalogenated Nucleophiles in Ni/Cr-Mediated Reactions: Synthesis of C1–C19 Building Block of Halichondrin Bs

  摘要：

  The C1-C19 building block 46 of halichondrin Bs was synthesized via a selective activation/coupling of beta-bromoenone 34 with aldehyde 35 in a Ni/Cr-mediated reaction. The first phase of study was a method development to effect a coupling of a naked vinylogous anion with an aldehyde. The study with the coupling of 9 + 10 -> 11 revealed: (1) beta-bromoenone 9b is a better nucleophile than the corresponding beta-iodo- and beta-chloroenones 9a,c; (2) (Me)(2)Phen(OMe)(2)center dot NiCl2 13b is a better Ni-catalyst than (Me)(2)Phen(H)(2)center dot NiCl2 13a; and (3) a low Ni-catalyst loading, for example, 0.05-0.1 mol % Ni-catalyst against 10 mol % Cr-catalyst, is crucial for an effective coupling. The second phase of study was a method development to realize a selective activation/coupling of polyhalogenated nucleophiles such as 34. The competition experiment of 10 + 9b over 10 + 31a-c revealed: (1) (Me)(2)Phen(OMe)(2)center dot NiCl2 13b is more effective than (Me)(2)Phen(H)(2)center dot NiCl2 13a for the required selective activation/coupling; (2) a low Ni-catalyst loading, for example, 0.05-0.1 mol % Ni-catalyst against 10 mol % Cr-catalyst, is crucial for discriminating beta-bromoenone 9b from the three types of vinyl iodides 31a-c. The third phase of study was an application of the developed method to execute the proposed coupling of 34 + 35 -> 36. For this application, a polyether-type Ni-catalyst 37c, readily soluble in the reaction medium, was introduced to achieve the selective activation/coupling with higher efficiency. With use of ion-exchange resin-based device, the coupling product 36 was transformed to the C1-C19 building block 46 of halichondrin Bs without purification/separation of the intermediates.

  The four major components present in scent gland extracts of the male Costa Rica longwing butterflies Heliconius cydno and Heliconius pachinus were identified as 12- and 14-membered macrolides containing a C18-carbon skeleton. By use of micro-reactions and spectrometric examinations, structural proposals were made and subsequently proven by synthesis, using ring-closing-metathesis as the key steps. These macrolides, (9Z,11E,13S)-octadeca-9,11-dien-13-olide (5, S-coriolide), (9Z,11E,13S,15Z)-octadeca-9,11,15-trien-13-olide (6), (9Z,13S)-octadec-9-en-13-olide (13), and (9Z,11S)-octadec-9-en-11-olide (25), are biosynthetically obviously derived from oleic, linoleic, and linolenic acids. Their absolute configurations were determined by gas chromatographic investigations on chiral phases, showing all to possess (S)-configuration.

• The Hexadehydro-Diels–Alder Cycloisomerization Reaction Proceeds by a Stepwise Mechanism

  cycloisomerization reaction proceeds in a stepwise manner-i.e., via a diradical intermediate. Judicious use of substituent effects was decisive. We prepared (i) a series of triyne HDDA substrates that differed only in the R group present on the remote terminus of the diynophilic alkyne and (ii) an analogous series of dienophilic alkynes (n-C7H15COC≡CR) for use in classical Diels-Alder (DA) reactions (with 1,3-cyclopentadiene)

  我们在此报告的实验表明，六氢-狄尔斯-阿尔德 (HDDA) 环异构化反应以逐步方式进行，即通过双自由基中间体。明智地使用取代效应是决定性的。我们制备了 (i) 一系列三炔 HDDA 底物，这些底物仅在亲二烯炔烃的远程末端存在的 R 基团不同，以及 (ii) 类似系列的亲二烯炔烃 (n-C7H15COC≡CR) 用于经典 Diels- Alder (DA) 反应（与 1,3-环戊二烯）。R 基团是 CF3、CHO、COMe/Et、CO2Me、CONMe2/Et2、H 和 1-丙炔基。测量了 HDDA 环化反应和简单 DA 环加成的相对速率。反应性趋势显示包含每个系列成员的 CF3（最慢的 HDDA 和几乎最快的 DA）和 1-丙炔基（最快的 HDDA 和最慢的 DA）的行为存在显着差异。这些差异可以通过将自由基稳定能量而不是吸电子效应作为 HDDA 反应的主要特征来解释。
