  Reaction of cyclic .alpha.-hydroxy epoxides with a strong base: a new 1,2-rearrangement, evidence for a carbenoid pathway.

  摘要：

  Several substituted five- and six-membered cyclic alpha,beta-unsaturated ketones are readily available by treatment of the corresponding alpha-hydroxy epoxides with an organolithium reagent. The reaction involves a new carbenoid 1,2-alkyl rearrangement. Evidence for the carbenoid intermediate has been obtained by an intramolecular trapping of the highly reactive species.

  Synthesis, in vitro acetylcholine-storage-blocking activities, and biological properties of derivatives and analogs of trans-2-(4-phenylpiperidino)cyclohexanol (vesamicol)

  摘要：

  Eighty-four analogues and derivatives of the acetylcholine-storage-blocking drug trans-2-(4-phenylpiperidino)-cyclohexanol (vesamicol) were synthesized, and their potencies were evaluated with the acetylcholine active-transport assay utilizing purified synaptic vesicles from Torpedo electric organ. The parent drug exhibits enantioselectivity, with (-)-vesamicol being 25-fold more potent than (+)-vesamicol. The atomic structure and absolute configuration of (+)-vesamicol were determined by X-ray crystallography. The absolute configuration of (-)-vesamicol is 1R,2R. Structure-activity evidence indicates that (-)-vesamicol does not act as an acetylcholine analogue. Alterations to all three rings can have large effects on potency. Unexpectedly, analogues locking the alcohol and ammonium groups trans-diequatorial or trans-diaxial both exhibit good potency. A potent benzovesamicol family has been discovered that is suitable for facile elaboration of the sort useful in affinity labeling and affinity chromatography applications. A good correlation was found between potencies as assessed by the acetylcholine transport assay and LD50 values in mouse.

• Oxygen transfer reactions from an Oxaziridinium tetrafluoroborate salt to Olefins
  作者：Xavier Lusinchi、Gilles Hanquet

  Oxaziridinium efficiently epoxidises olefins. It reacts as an electrophilic reagent and does not transfer its oxygen to deactivated double-bonds or carbonyl functions. Epoxidation of cyclic allylic acetates shows a remarkable diastereoselectivity leading to the syn isomer. We propose that the epoxidation reaction proceeds through a one-step process.

  Good cis selectivity is observed in the epoxidation of the cyclic allylic alcohols 2-cyclopentenol and 2-cyclohexenol due to a hydroxy-directing effect through hydrogen bonding; however, for 2-cycloheptenol and 2-cyclooctenol hydrogen bonding is ineffective and steric interactions cause a higher trans selectivity. The conformationally fixed cis- and trans-5-tert-butyl-2-cyclohexenols serve as suitable

  对于一系列的3-烷基取代的环己烯，已经评估了在用甲基三氧or /脲/过氧化氢加合物（MTO / UHP）进行环氧化时，烯丙基取代基的空间效应。的反式与取代基的大小选择性增加，并且非对映选择性遵循塔夫脱（的立体取代基常数的良好的线性相关性ë小号）或Charton（ν）。由于通过氢键的羟基引导作用，在环状烯丙基醇2-环戊烯醇和2-环己烯醇的环氧化中观察到良好的顺式选择性。但是，对于2-环庚烯醇和2-环辛烯醇，氢键无效，空间相互作用会导致更高的反式选择性。构象固定的顺式和反式-5-叔丁基-2-环己烯醇用作合适的底物，用于测量在这些环氧化反应中的氧转移的过渡态的二面角。因此，MTO / UHP氧化剂有利于一个准赤道有效氢键（羟基-组指向性）的羟基的结构，以类似于米氯过苯甲酸（米-CPBA）和二甲基二（DMD），和一个二面角约。建议130°。
