  A new asymmetric synthesis of 2,6-cis-disubstituted 4-methylenepiperidines: total synthesis of (+)-alkaloid 241D and (+)-isosolenopsin A

  摘要：

  A highly diastereoselective synthesis of 2,6-cis-disubstituted-4-methylenepiperidines based on a Mannich type intramolecular cyclization of an allylsilane on an iminium ion is described. The synthetic potential of this methodology is demonstrated by the enantioselective synthesis of two natural piperidine alkaloids: (+)-alkaloid 241 D and (+)-isosolenopsin A. (C) 2005 Elsevier Ltd.

  A protocol for rapid access to the relative and absolute configurations of the solenopsins, the venom alkaloids of fire ants (Solenopsis spp.), was developed based on chiral capillary gas chromatography. The synthesis of racemic mixtures of 2-methyl-6-alkylpiperidines and the isolation of natural (2R,6R)- and (2R,6S)-2-methyl-6-undecylpiperidines allowed for the standardization of the chromatographic

  functionalized organolithium compounds derived from 5-chloro-2-methoxy-1-pentene and 6-chloro-2-methoxy-1-hexene to N-tert-butanesulfinyl aldimines imines, and a subsequent hydrolysis of the enol ether moiety, yielded different δ- and ε-amino ketone derivatives, respectively, in moderate yields and diastereoselectivities. The application of these compounds in organic synthesis was demonstrated by the

  Two strategies, "hydrogenation-hydride reduction" and. "quaternization-hydride reduction", are reported, that make use of mild reaction conditions (room temperature) to efficiently remove the N-pyridin-2-yl directing group from a diverse set of C-2-substituted piperidines that were synthesized through directed Ru-catalyzed Sp(3) C-H functionalization. The deprotected products are obtained in moderate to good overall yields irrespective of the strategy followed, indicating that both methods are generally. equally effective. Only in the case of 2,6-disubstituted piperidines, could the "quaternization-hydride reduction" strategy not be used. The "hydrogenation-hydride reduction" protocol was successfully applied to trans- and cis-2-methyl-N-(pyridin-2-yl)-6-undecylpiperidine in a short synthetic route toward (+/-)-solenopsin A (trans diastereoisomer) and (+/-)-isosolenopsin A (cis diastereoisomer). The absolute configuration of the enantiomers of these fire: ant alkaloids could be determined via VCD spectroscopy.
