  通过ECD和UV-vis揭示了共轭氯环丙基链炔烃的同步键分子动力学。

  摘要：

  与炔烃共轭的氯环丙烷（CCP）存在于海洋海绵的独特的聚酮化合物天然产物家族中。几种CCP的光学富集类似物的合成以及它们的UV-vis光谱和电子圆二色性（ECD）光谱的测量揭示了异常强的超共轭，该超共轭将环丙基C-C键约束并与远侧烯键的π平面对齐。该对准施加至少5.0kcal·mol -1的旋转障碍。手性CCP中红移棉效应的比较表明，该屏障独立于烯烃取代基，并为其他含CCP天然产物的分配建立了经验规则。

  Synthetic Studies on the trans-Chlorocyclopropane Dienyne Side Chain of Callipeltoside A

  摘要：

  [GRAPHICS]Enantiomerically enriched trans-chlorocyclopropanemethanol was obtained by lipase kinetic resolution of dichlorocyclopropanemethanol 3, followed by reduction. The sp-sp(2) bond of the trans-chlorocyclopropane dienyne side chain of callipeltoside A was constructed via a Stifle coupling reaction of 1,1-dibromo-1-alkene 7 and a vinylstannane in a highly dipolar solvent capable of promoting HBr elimination to give internal alkynes.

  chlorocyclopropane macrolides, phorbasides A and B, have been characterized from the sponge Phorbas sp. that previously yielded phorboxazoles A and B. We describe the assignment of the absolute configuration of the trans-chlorocyclopropane ring that exploits a CD Cotton effect arising from hyperconjugation to the ene-yne chromophore. Phorbasides and callipeltoside A share the same macrolide configurations but, unexpectedly

  两种新的氯环丙烷大环内酯，佛巴苷 A 和 B，已从海绵 Phorbas sp. 中得到表征。先前产生佛盒唑 A 和 B。我们描述了反式氯环丙烷环的绝对构型的分配，该环利用了由于与烯-炔生色团的超共轭而产生的 CD 棉花效应。Phorbasides 和 callipeltoside A 具有相同的大环内酯构型，但出人意料的是，环丙烷构型相反。
• Addition of Cl₂C:  to (−)-<i>O</i>-Menthyl Acrylate under Sonication−Phase-Transfer Catalysis. Efficient Synthesis of (+)- and (−)-(2-Chlorocyclopropyl)methanol

  Dichlorocyclopropanation of (-)-O-menthyl acrylate under conditions of phase-transfer catalysis (CHCl3, KOH, tetramethylammonium bromide), with sonication, gives excellent yields (85-94%) of the corresponding dichlorocyclopropanecarboxylate ester compared to thermal conditions (90 degrees C, 56%). No diastereoselectivity was observed, but one isomer was isolated pure by fractional crystallization. The measured kinetic isotope effect (initial rate (CHCl3)/rate (CDCl3) similar to 1.7) suggests deprotonation of CHCl3 as the rate-limiting step.
