    Enantioselective Synthesis of α,β-Disubstituted-β-amino Acids
    摘要:
    Highly diastereoselective and enantioselective addition of N-benzylhydroxylamine to imides 17 and 20-30 produces alpha,beta-trans-disubstituted N-benzylisoxazolidinones 19 and 31-41. These reactions proceed in 60-96% ee with 93-99% de's using 5 mol % of Mg(NTf2)2 and ligand 18. The product isoxazolidinones can be hydrogenolyzed directly to provide alpha,beta-disubstituted-beta-amino acids.

    The nucleophilic γ-phenylation and γ-alkylation of α,β-unsaturated amides have been developed. This umpolung reaction allows the regioselective introduction of phenyl and alkyl groups to a vinylketene N,O-acetal, which is generated in situ from an α,β-unsaturated N-alkoxyamide, followed by N-O bond cleavage in a two-step, one-pot process.
    已经开发出α,β-不饱和酰胺的亲核性γ-苯基化和γ-烷基化。通过这种不连续的反应,可以将苯基和烷基区域选择性地引入乙烯基乙烯酮N,O-乙缩醛中,该基团由α,β-不饱和N-烷氧基酰胺原位生成,然后通过两步,一锅过程。
