  • Enantioselective Synthesis of Piperidine, Indolizidine, and Quinolizidine Alkaloids from a Phenylglycinol-Derived δ-Lactam
    作者:Mercedes Amat、Núria Llor、José Hidalgo、Carmen Escolano、Joan Bosch
    DOI:10.1021/jo0266083
    日期:2003.3.1
    Starting from a common lactam, (3R,8aS)-5-oxo-3-phenyl-2,3,6,7,8,8a-hexahydro-5H-oxazolo[3,2-a]pyridine (1), or its enantiomer, the enantioselective synthesis of 2-alkylpiperidines and cis- and trans-2,6-dialkylpiperidines is reported. The potential of this approach is illustrated by the synthesis of the piperidine alkaloids (R)-coniine, (2R,6S)-dihydropinidine, (2R,6R)-lupetidine, and (2R,6R)-solenopsin

  • Enantioselective Synthesis of 3,3-Disubstituted Piperidine Derivatives by Enolate Dialkylation of Phenylglycinol-Derived Oxazolopiperidone Lactams
    作者:Mercedes Amat、Oscar Lozano、Carmen Escolano、Elies Molins、Joan Bosch
    DOI:10.1021/jo070397q
    日期:2007.6.1
    dialkylation of simple phenylglycinol-derived oxazolopiperidone lactams is studied. High stereoselectivities in the generation of the quaternary stereocenter are obtained by the appropriate choice of both the configuration of the starting lactam and the order of introduction of the substituents. The usefulness of the methodology is illustrated by the conversion of some of the dialkylated lactams into known synthetic

  • Microwave-Assisted Domino Hydroformylation without Syngas
    作者:Maurizio Taddei、Elena Cini、Etienne Airiau、Nicolas Girard、André Mann、Jessica Salvadori

    日期:2011.1
    Hydroformylation is a powerful reaction that has suffered for some negative prejudices related to the use of gaseous H2 and CO. Now it is possible to carry out hydroformylation and different cyclohydrocarbonylations, even on complex substrates, using aqueous formalin as H2 and CO surrogate in few minutes under microwave irradiation. The catalytic system developed by Morimoto (Rh/BINAP for decomposition of formaldehyde and Rh/Xantphos for hydroformylation) is compatible with microwave dielectric heating and with complex substrates containing ligand atoms allowing rapid domino hydroformylation cyclization reactions without using the external supply of gaseous H2 and CO (gas cylinder) and without any particular safety limitation or device.
    氢甲酰化是一种强大的反应,但一直因使用气态H2和CO而饱受一些负面偏见。现在,在微波辐射下,只需几分钟,就可以使用水合甲醛作为H2和CO的替代品,在复杂的底物上进行氢甲酰化和不同的环羟基化反应。森本开发的催化系统(用于分解甲醛的Rh/BINAP和用于氢甲酰化的Rh/Xantphos)与微波介电加热和含有配体原子的复杂底物兼容,无需使用外部气态H2和CO(气瓶)供应,也无需任何特殊的安全限制或装置,即可快速进行多米诺氢甲酰化环化反应。

  • Enantioselective syntheses of the indole alkaloid (+)-R-decarbomethoxytetrahydrosecodine and its enantiomer
    作者:Mercedes Amat、Grigorii Pshenichnyi、Joan Bosch、Elies Molins、Carles Miravitlles
    DOI:10.1016/0957-4166(96)00405-3
    日期:1996.11
    The alkaloid (+)-R-decarbomethoxytetrahydrosecodine (+)-1 has been synthesized by alkylation of (R)-3-ethylpiperidine with 3-(2-bromoethyl)-2-ethylindole (7). The required enantiopure piperidine was prepared by alkylation of the chiral non-racemic oxazolopiperidone (+)-trans-8 followed by reduction of the lactam carbonyl group and removal of the chiral auxiliary, whereas tryptophyl bromide 7 was obtained
