  Spiroaminal model systems of the marineosins with final step pyrrole incorporation

  摘要：

  In this Letter, we describe a short, six step enantioselective route to spiroaminal lactam model systems reminiscent of marineosins A and B that has been developed starting from either (R)- or (S)-hydroxysuccinic acid, respectively, in similar to 9% overall yield. This route enables late stage incorporation of the pyrrole ring at C5 via nucleophilic displacement of an iminium triflate salt. (C) 2013 Elsevier Ltd. All rights reserved.
