  • Etude des aldimines lithiees
    作者:Jean-Francois Le Borgne
    DOI:10.1016/s0022-328x(00)80603-8
    日期:1976.12
    Aldimines are conveniently metallated, at a position α to the functional group, by using very powerful bases i.e. activated lithium dialkylamides generated in situ from lithium and a secondary amine in benzene/hexamethylphosphoric triamide. The anions obtained are alkylated with various ω,ω′-dihalogenoalkanes to give, after aqueous acid hydrolysis, good yields of ω-halogenated aldehydes and dialdehydes
    通过使用非常强大的碱,即由锂和仲胺在苯/六甲基磷三酰胺中原位生成的活化的二烷基酰胺化锂,可以方便地在官能团的位置α处将金属亚胺金属化。酸水解后,所得的阴离子用各种ω,ω'-二卤代烷烃烷基化,可得到ω-卤代醛和二醛的良好收率。

  • A New Enantioselective Total Synthesis of Natural Vincamine<i>via</i>an Intramolecular<i>Mannich</i>Reaction of an Silyl Enol Ether
    作者:Wolfgang Oppolzer、Hartmut Hauth、Paul Pfäffli、Roland Wenger
    DOI:10.1002/hlca.19770600533
    日期:1977.7.13
    AbstractNatural Vincamine (1) has been synthesized in an enantioselective manner starting from the ethylpentenal7. In the key step a mixture of the diastereoisomeric racemates,14and15, was directly obtained from the silyl enol ether11and the dihydro‐β‐carboline12by the way of an intramolecularMannichreaction of the intermediate13(Scheme 4). The undesired stereoisomers,14and15b, were recycled to15ausing the related reversibleMannichreaction18 ⇄ 14 + 15, followed by crystallization of the salt from15aand (+)malic acid.15awas converted to natural vincamine (1) in several steps including the known transformation20→1.
