  Asymmetric Syntheses of N-Boc 2-Substituted Pyrrolidines and Piperidines by Intramolecular Cyclization

  摘要：

  Asymmetric lithiation-substitutions by n-BuLi/(-)-sparteine with the N-Boc-N-(3-halopropyl)allylamines 1-4 provide the N-Boc-2-alkenylpyrrolidines (S)-5, (S)-6, and (S)-7 in yields of 31-93% with enantiomeric ratios (ers) from 65:35 to 90:10. These reactions are shown to involve an initial asymmetric deprotonation, but the enantiodetermining step is a subsequent asymmetric cyclization under the influence of the chiral ligand. Extension to formation of a piperidine is illustrated by reaction of N-Boc-(4-chlorobutyl)cinnamylamine (9) to afford (S)-N-Boc-2-(trans-beta-styryl)piperidine ((S)-10) in 68% yield with an enantiomeric ratio (er) of 84:16. Analogous reactions with epoxide ring openings of N-Boc-N-(oxaalkenyl)benzylamines 11 and 12 afford the corresponding N-Boc-2-phenyl-3-(hydroxymethyl)pyrrolidine (13) in 67% yield with a diastereomeric ratio (dr) of 50:50 and ers of 97:3 and 95:5 and the corresponding N-Boc-2-phenyl-3-(hydroxymethyl)piperidine (14) in 29% yield with a dr of 86:14 and ers of 81:19 and 86:14.

  Pd- N -heterocyclic carbene catalyzed synthesis of piperidine alkene–alkaloids and their anti-cancer evaluation

  摘要：

  A facile synthesis of piperidine alkene-alkaloids including natural (+)-Caulophyllumine B in high yields has been developed by Heck cross-coupling reaction catalyzed by simple in situ formed palladium-N-heterocyclic carbenes (Pd-NHCs). Formation of Pd(0) nanoparticles has been noticed during the reaction course. The synthesized piperidine alkene-alkaloids were evaluated for in vitro anti-cancer activity against a panel of human tumor cell lines of lung, breast and ovarian. Several of these piperidine alkene-alkaloids were found to possess highest growth inhibition activity than the standard drug cisplatin and support the concept to modulate drug receptor interaction.

  nonracemic Betti base as a chiral auxiliary. The key step is that the auxiliary residue was removed by a novel base-catalyzed N-debenzylation via a formation of o-quinone methide mechanism in stead of the traditional hydrogenolysis, by which the alkene or alkyne groups survived. By this method, ten 2-alkene- or 2-alkyne-containing chain substituted piperidines were prepared on the gram scale within

  通过使用非外消旋的Betti碱作为手性助剂，建立了制备对映体纯的含2个烯烃或2个炔烃的链取代哌啶的一般方法。关键步骤是代替传统的氢解反应，通过传统的氢解反应，通过邻甲基苯甲酸甲酯的形成，通过新颖的碱催化的N-脱苄基反应去除了辅助残基。通过这种方法，在数小时内以克为单位制备了十个含2-烯烃或2-炔烃的链取代的哌啶。为了证明该方法的有效性和产品的多功能性，使用（S）-2-烯丙基完成了天然生物碱（+）-peltierine，（-）-lasubine II和（+）-cermizine C的总合成--N -Boc-哌啶为通用成分。
