  • One-pot multiple reactions: asymmetric synthesis of 2,6-cis-disubstituted piperidine alkaloids from chiral aziridine
    作者:Nagendra Nath Yadav、Jihye Choi、Hyun-Joon Ha
    DOI:10.1039/c6ob00806b
    日期:——
    A divergent, new, and highly stereoselective synthesis of cis-2,6-disubstituted piperidine natural products including isosolenopsins, deoxocassine, and spectaline was achieved from chiral aziridine decorated with appropriate alkyl chains for isosolenopsins or alkynyl groups for deoxocassine and spectaline at C2. The characteristic feature of this synthesis is one-pot sequential reactions under atmospheric
    由手性氮丙啶制备了顺式-2,6-二取代哌啶天然产物(包括异戊香辛素,去氧卡西汀和壮观碱)的发散,新的且高度立体选择性的合成,该手性氮丙啶装饰有合适的异戊香辛素烷基链或炔氧基(在C2处为脱氧卡西汀和壮观碱)。该合成的特征是在大气氢下进行一锅法连续反应,包括炔烃的还原(对于脱氧卡西汀和甲壳碱),氮丙啶的还原性开环,脱苄基作用和高产率的分子内还原胺化。必备的氮丙啶是从可商购的(2 S)-羟甲基氮丙啶通过氧化,维蒂希(Wittig)烯化反应和格利雅(Grignard)反应制得异麦芽孢素,或通过底物控制的炔基锂加成生成脱氧卡西汀和甲壳素。
  • Controlled reduction of 5-alkyl-3-phenyl-2,3,5,6,7,8-hexahydro-oxazolo[3,2-a]pyridin-4-ylium iodide: enantioselective synthesis of (−)-dihydropinidine and (+)-indolizidine 167B
    作者:Luis F. Roa、Dino Gnecco、Alberto Galindo、Joel L. Terán

    reduction of (+)-(3R,5S)-5-methyl- and (+)-(3R,5S)-5-n-propyl-3-phenyl-2,3,5,6,7,8-hexahydro-oxazolo[3,2-a]pyridin-4-ylium iodide 1 and 2 to generate (3R,5S)-5-methyl- and (3R,5S)-5-n-propyl-3-phenyl-2,3,5,6,7,8-hexahydro-oxazolo[3,2-a]pyridine 3 and 4, respectively, is reported. In addition, an enantioselective synthesis of ()-(2R,6S)-dihydropinidine and (+)-(2S,6S)-indolizidine 167B starting from

  • Diastereoselective Addition of Grignard Reagents to Chiral 1,3-Oxazolidines Having a N-Diphenylmethyl Substituent.
    作者:Takayasu YAMAUCHI、Hiroshi TAKAHASHI、Kimio HIGASHIYAMA
    DOI:10.1248/cpb.46.384
    日期:——
    Chiral 1, 3-oxazolidines having a diphenylmethyl group at the 3-position of the oxazolidine ring as a bulky substituent were synthesized. The reaction of Grignard reagents with the chiral 1, 3-oxazolidines afforded the corresponding amines with very high diastereoselectivity. Furthermore, the method for the synthesis of optically active amines was applied to the asymmetric synthesis of (-)-dihydropinidine, a piperidine alkaloid.
    具有位于恶唑烷环3位的二苯甲基作为大体积取代基的手性1,3-恶唑烷类化合物被合成出来。手性1,3-恶唑烷与格氏试剂反应,以极高的非对映选择性获得了相应的胺。此外,制备光学活性胺的方法被应用于(-)-二氢哌啶生物碱的对映异构合成中。
  • Enantioselective Syntheses of 2-Alkyl-, 2,6-Dialkylpiperidines and Indolizidine Alkaloids Through Diastereoselective Mannich-Michael Reactions
    作者:Markus Weymann、Waldemar Pfrengle、Dieter Schollmeyer、Horst Kunz
    DOI:10.1055/s-1997-3185
    日期:1997.10
    Aldimines of 2,3,4,6-tetra-0-pivaloyl-β-D-galactosylamine react with 1-methoxy-3-trimethylsilyloxybuta-1,3-diene in a Mannich-Michael condensation reaction sequence to give 2-substituted N-galactosyl-5,6-dehydropiperidin-4-ones 3 with high diastereoselectivity. The X-ray analysis of the 2-propyl derivative 3a proved (R)-configuration of the major diastereomer and led to the correction of our earlier assignment of configuration for (-)-coniine hydrochloride 9a obtained from this intermediate. Despite their low reactivity, these enaminones 3 can be converted into chiral 2,6-cis-disubstituted piperidinones 12 with high stereoselectivity by reaction with organocuprates in combination with hard electrophiles. Enantiomerically pure alkaloids such as (-)-dihydropinidine and gephyrotoxine 167B have been synthesized according to this methodology.
    2,3,4,6-四-O-特戊酰基-β-D-半乳糖胺的烯胺与1-甲氧基-3-三甲基硅氧基丁-1,3-二烯在曼尼希-迈克尔缩合反应序列中反应,以高非对映选择性得到2-取代的N-半乳糖基-5,6-脱氢哌啶-4-酮3。2-丙基衍生物3a的X射线分析证实了主要非对映异构体的(R)构型,并纠正了我们之前对该中间体得到的(-)-毒芹碱盐酸盐9a的构型分配。尽管这些烯胺酮3的反应性较低,但通过与有机铜酸盐和硬亲电试剂的反应,可以高立体选择性地将其转化为手性的2,6-顺式-二取代哌啶酮12。根据这一方法,已经合成了高对映纯度的生物碱,如(-)-二氢矮牵牛素和gephyrotoxine 167B。
  • Regio- and Stereoselective Monoamination of Diketones without Protecting Groups
    作者:Robert C. Simon、Barbara Grischek、Ferdinand Zepeck、Andreas Steinreiber、Ferdinand Belaj、Wolfgang Kroutil
    DOI:10.1002/anie.201202375
    日期:2012.7.2
    Hitting the right target: Differentiation between two keto moieties was accomplished by a regio‐ and enantioselective bioamination employing ω‐transaminases. Using 1,5‐diketones as substrates gave access to the optically pure 2,6‐disubstituted piperidine scaffold. The approach allowed the shortest synthesis of the alkaloid dihydropinidine, as well as its enantiomer, by choosing an appropriate ω‐transaminase
    达到正确的目标:通过使用ω-转氨酶进行区域和对映选择性生物胺化,可实现两个酮基部分的区分。使用1,5-二酮作为底物可以进入光学纯的2,6-二取代的哌啶骨架。通过选择合适的ω-转氨酶,该方法可以最短地合成生物碱二氢吡啶及其对映体。
