Starting from bicyclic hemiesters obtained by enzymatic hydrolysis of meso
diesters, polyfunctionalized cyclohexanes were prepared with high stereosel
ectivity in a synthetic strategy of few steps involving a Curtius reaction
followed by a retro Michael ring opening reaction and reductions. This sequ
ence offers a versatile approach to the synthesis of various aminocarba-sug
ars.
