摘要
The synthesis of fully protected beta-methyl aspartic acids from (+/-)-glutamic anhydride has been achieved by means of ring contraction of the derived nickelacycle followed by insertion of an isocyanide. The intermediate five-membered ring nickelacycles were isolated and characterized spectroscopically.
