Catalytic, enantioselective propargyl- and allenylation reactions of α-imino ester have been achieved by means of the [Cu(MeCN)4]ClO4/(R)-tol-BINAP catalyst to afford the corresponding propargyl- and allenyl-substituted α-amino acid derivatives, respectively, in good yields with good enantiomeric excesses.
已经通过 [Cu(MeCN)4]ClO4/(R)-tol-BINAP 催化剂实现了 α-亚氨基酯的催化、对映选择性炔丙基和烯丙基化反应,得到相应的炔丙基和烯丙基取代的 α-氨基酸衍生物,分别以良好的收率和良好的对映体过量。
