  Synthesis of the C-13 Side Chain Precursors of the 9-Dihydrotaxane Analogue ABT-271

  摘要：

  [GRAPHICS]N-Boc-L-Leucinol was converted to two C-13 side chain precursors of the 9-dihydrotaxane analogue ABT-271. The trans-oxazolidine acid 4 and the cis-Boc-lactam 2b were prepared in 44% and 40% overall yield, respectively, and with excellent (>98%) stereochemical purity.

• A Versatile Approach to <i>N</i>-Boc-statine and <i>N</i>-Boc-norstatine Based on the Reduction of 1-Trialkylsilyl Acetylenic Ketones. Strong Remote Effect of the C(1) Substituent on the Stereoselectivity

  日期：1999.12.1

  [GRAPHICS]An efficient, unified approach to chiral, protected beta-hydroxy gamma-amino and alpha-hydroxy beta-amino acids derived from Boc-L-leucine has been accomplished on the basis of the oxazaborolidine-controlled, stereoselective reduction of 1-trialkylsilyl acetylenic ketones; stereoselectivity in the reduction step has shown strong dependence upon C(1) substitution.
