  Chemo- and Diastereoselective Reduction of .beta.-Enamino Esters: A Convenient Synthesis of Both cis- and trans-.gamma.-Amino Alcohols and .beta.-Amino Esters

  摘要：

  Convenient procedures for the chemo- and diastereoselective reduction of beta-enamino esters 1 are described. Both cis- and trans-gamma-amino alcohols 2 or beta-amino esters 3 can be prepared by reduction of beta-enamino esters 1, readily available starting materials, with the use of inexpensive reagents Nali-PrOH or NaHbB(OAc)(3)/AcOH, respectively, and the appropriate reduction conditions. The mechanisms and diastereoselectivities for the reductions are discussed. The relative configurations and conformations of the diastereoisomeric gamma-amino alcohols 2 and beta-amino esters 3 obtained are established by H-1 and C-13 NMR study and unequivocally set by their cyclic derivatives tetrahydro-1,3-oxazines 4.

• Enantioselective Organocatalytic Aza-Ene-Type Domino Reaction Leading to 1,4-Dihydropyridines
  作者：Artur Noole、Maria Borissova、Margus Lopp、Tõnis Kanger

  DOI：10.1021/jo200095e

  日期：2011.3.18

  A new general methodology was developed to access highly enantiomerically enriched 1,4-dihydropyridines (DHPs) 3 via an organocatalytic asymmetric aza-ene-type cascade reaction, cocatalyzed by (S)-diarylprolinol−TMS ether V and benzoic acid (BA). Both aliphatic and aryl enals 1 reacted smoothly with enaminones and β-enamino esters 2, affording highly functionalized 1,4-DHPs 3 in high enantioselectivities
