The use of a germene for the synthesis of esters of α-germyl-substituted α-amino acid and α-aminophosphonic acid†
Abstract
The first α-germyl-substituted α-amino ester and α-germyl-substituted α-aminophosphonic ester have been synthesized by a one-pot reaction between the germene Mes2GeCR2
(CR2
= fluorenylidene) and the iminoester or iminophosphonate Ph(H)C
NCH2–Y (Y = COOMe, P(O)(OEt)2).
