  Synthesis of chiral non-racemic azetidines by lipase-catalysed acetylations and their transformation into amino alcohols: precursors of chiral catalysts

  摘要：

  Azetidinic mono-acetate 7, diol 6b and di-acetate 10a were prepared with high e.e. using PPL-catalysed acetylations. The absolute configurations of all new enantioenriched compounds were assigned by chemical correlation with known compounds. Mono-acetate 7 was then transformed into 30, an amino alcohol of noteworthy potential interest since it represents an interesting precursor for chiral catalysts, such as 32.
