    Enantioselective synthesis of 2-sulfenylated aldehydes: Alkylation of sulfenylated acetaldehyde SAMP-hydrazones
    摘要:
    A practical and efficient enantioselective synthesis of 2-sulfenylated aldehydes (S)-6 is described, based on the alpha-alkylation of sulfenylated acetaldehyde SAMP hydrazones (S)-4, easily prepared from bromoacetaldehyde diethyiacetal 1, thiols and (S)-1-amino-2-methoxymethyl-pyrrolidine (SAMP). A chemoselective oxidative cleavage of the intermediate SAMP hydrazones (S,S)-5 with ozone gives rise to the title compounds (S)-6 in good overall yields and high enantiomeric excesses of up to 97%.

  • α-Heterosubstituted Aldehydes in Organic Synthesis. Enantioselective Approaches to New Analogues of Mevinic Acids
    作者:Dieter Enders、Frank Burkamp
    DOI:10.1135/cccc20030975
    日期:——

    Various aldol approaches towards the asymmetric synthesis of the lactone moiety of HMG-CoA-reductase inhibitors are described. Auxiliary controlled as well as catalytic aldol reactions resulted only in modest to low selectivities, whereas 1,2-additions to readily available highly enantiomerically enriched α-heterosubstituted aldehydes yielded δ-hydroxy-β-ketoesters with a high degree of diastereocontrol and in good chemical yields. The novel mevinic acid analogues could then be obtained bysyn-reduction of the addition products.

    本文描述了对HMG-CoA还原酶抑制剂的内酯部分进行不对称合成的多种醛缩反应方法。辅助控制和催化醛缩反应只能得到适度至低的选择性,而对易得到的高对映异构体α-杂基取代醛的1,2-加成则产生了具有高度对映异构体控制和良好化学收率的δ-羟基-β-酮酸酯。然后通过对加成产物的syn-还原获得了新型的梅维酸类似物。

    Optically active α-sulfenylated aldehydes , readily available by asymmetric alkylation of α-sulfenylated acetaldehyde-SAMP-hydrazones followed by chemoselective oxidative removal of the chiral auxiliary, can be transformed into vicinal thioether alcohols 2, 5 and 6 by diastereoselective 1,2-addition using various carbon nucleophiles.
