C4-building blocks for medicinal chemistry. The enzymatic kinetic resolution based synthesis of 1 and ent-1 utilises inexpensive, commercially available starting materials. It is based on enantiomeric resolution of rac-cyclopropane carboxylic esters using esterase from Streptomyces diastatochromogenes. Bothenantiomers of 1 were prepared selectively in high overall yield over nine steps, starting from
