Reaction of Magnesium Carbenoids with N-Lithio Arylamines: A Novel Method
for Generation of Non-Stabilized α-Amino-Substituted Carbanions and a New
49- 082 Synthesis
of α-Amino Acid Derivatives. — Reaction of 1-chloroalkyl phenyl sulfoxides (I) according to A) affords magnesium carbenoids which react with N-lithio
amines (II). Quenching of the resulting intermediates with ester (III) or CD3OD results
in a novel synthesis of α-amino acid derivatives or deuterated arylamines. —
