  A versatile approach to pyrrolidine azasugars and homoazasugars based on a highly diastereoselective reductive benzyloxymethylation of protected tartarimide

  摘要：

  A highly diastereoselective synthesis of enantio-enriched all trans-3,4-dibenzyloxyl-5-benzyloxymethyl-2-pyrrolidinone 13a was developed based on SmI2-mediated benzyloxymethylation of O,O'-dibenzyltartarimide. The versatility of 13a and its antipode as the key building blocks for the asymmetric synthesis of pyrrolidine azasugars and homoazasugars has been demonstrated by elaborating them into naturally occurring DAB 1 (1), LAB 1 (2), N-hydroxyethyl-DAB 1 (4), 6-deoxy-DMDP 7, and 5-epi-radicamine B 36 as well as the reductive ring-opening product 35.

• A concise and divergent approach to radicamine B and hyacinthacine A3 based on a step-economic transformation

  Based on our recently developed step-economic methodology of reductive alkylation of lactams/amides, we have developed a two-step synthesis of azasugar radicamine B (2a) and a four-step synthesis of azasugar hyacinthacine A(3) (5) from the common chiral building block 12. Hantzsch ester (HEH) was used as a milder hydride donor in the one-pot stereoselective reductive alkylation of lactam 12. The Wacker oxidation of fully substituted pyrrolidine derivative 2,5-trans-17 led to the synthesis of hyacinthacine A(3) (5). Compound 2,5-trans-17 could also serve as a plausible key intermediate for the synthesis of broussonetine sub-class of azasugars. (C) 2012 Elsevier Ltd. All rights reserved.
