    描述:
    6-methoxy-3-methyl-4-chromanone (1R,2R,3S,4S)-3-Amino-1,7,7-trimethyl-bicyclo[2.2.1]heptan-2-ol氢气lithium hexamethyldisilazane 作用下, 以 四氢呋喃正己烷乙酸乙酯 为溶剂, 反应 9.0h, 生成 (R)-6-methoxy-3-methyl-4-chromanone

    名称:
    Access to racemic and enantioenriched 3-methyl-4-chromanones: catalysed asymmetric protonation of corresponding enolic species as the key step
    摘要:
    Bronsted acids induced the intramolecular cyclisation of 3-aryloxypropanoic esters affording 3-methyl-4-chromanones, which have been transformed into the corresponding racemic benzyl beta-oxoesters. These latter esters, in the presence of hydrogen and catalytic amounts of both palladium and (endo, endo) aminobomeol, led to optically active chromanones with up to 75% ee through a deprotection-decarboxylation-protonation cascade reaction.
