  A flexible non-amino acid-based formal asymmetric synthesis of naturally occurring (2R,3S)-2-aminotetradeca-5,7-dien-3-ol: observation of a remarkable protecting group effect

  摘要：

  A flexible non-amino acid-based formal asymmetric synthesis of naturally occurring antimicrobial (2R,3S)-2-aminotetradeca-5,7-dien-3-ol is reported. The method features a flexible and highly regioselective Grignard addition to (S)-malimide followed by a trans-diastereoselective reductive deoxygenation. The scope and limitations of the highly regio and diastereoselective reductive alkylation of malimides were defined. A remarkable protecting group effect on the regio and diastereoselective reductive alkylation of malimides was observed. (C) 2003 Published by Elsevier Ltd.

  A Cu-catalyzed asymmetric kinetic boron conjugate addition of γ-substituted α,β-unsaturated γ-lactams followed by oxidation is reported with good results. This strategy provides an efficient access to valuable enantioenriched α,β-unsaturated γ-lactams bearing simple γ-alkyl or aryl substituents, which showed inhibitory activities against cisplatin-sensitive ovarian cancer cells A2780. A new Lewis acid
