The preparation of the diastereoisomers of 1-amino-2-bromocyclopropanecarboxylic acid is described using the methyl (1RS, 5SR)-2-oxo-3-oxabicyclo[3.1.0]hexane-1-carboxylate 5 as starting material. The key step is the oxidation of 9 with subsequent radical introduction of bromine according to the Barton procedure. The 2-bromo-cyclopropanecarboxylates cis-11 and trans-11 were obtained as diastereoisomer

The preparation of optically active 1-amino-2-(hydroxymethyl)cyclopropanecarboxylic acid has been achieved by a route involving cycloalkylation of dimethyl malonate with epichlorohydrin and subsequent Hofmann rearrangement. The reaction of epichlorohydrin with nucleophiles may occur al either electrophilic site, epoxide or halide. Based on the absolute configuration of the starting materials and the
