SN2 displacement at the quaternary carbon center: a novel entry to the synthesis of α,α-disubstituted α-amino acids
A novel method for the SN2 reaction on quaternarycarbon atoms using bis(p-nitrophenyl)phosphorazidate has been developed. Chiral tertiary alcohols were directly converted into the corresponding chiral tertiary azides with complete inversion of configuration. Several α,α-disubstituted α-amino esters or amino acids were prepared through the conversion of azides to the corresponding amines by catalytic
已开发出一种使用双(对硝基苯基)磷叠氮酸酯在季碳原子上进行S N 2反应的新方法。手性叔醇被完全转化为构型,直接转化为相应的手性叔叠氮化物。通过催化氢化将叠氮化物转化为相应的胺,可以制备几种α,α-二取代的α-氨基酯或氨基酸。
