  Synthesis of novel chiral hydrobenzoin mono-tert-butyl ethers derived from m-hydrobenzoin and their application as chiral auxiliaries in the diastereoselective reduction of α-keto esters

  摘要：

  Three m-hydroberizoin derived chiral hydrobenzoin mono-tert-butyl ethers were synthesized by a new, reaction pathway and tested as chiral auxiliaries in the L-selectride (R) mediated stereoselective reduction of their corresponding phellyl glyoxylates. As a result, improved stereoselectivities of up to a ratio of 92:8 compared to 84:16 with the initially examined analogous benzyl ether were achieved. (c) 2005 Elsevier Ltd. All rights reserved.
