A Simple Synthesis of 1-Aminocyclopropane-1-carboxylic acid Conversion of N-Carbobenzyloxy-L-glutamic acid α-methylester (Z-L-glu(OH)OCH3, 1) into the bromo derivative 2 and subsequent γ-elimination by the use of sodium hydride leads to the fully protected synthon 3 in good yields. Deprotection by sodium hydroxide and hydrogenolysis yields almost quantitively the key substance 5.
