Biocatalytical Transformations- VI. The 4-Acetamido-cyclopent-2-ene Carboxylate Route Revisited: Synthesis of (+)- and (-)-Aristeromycin

Csuk, Rene,Doerr, Petra

, p. 5789 - 5798 (2007/10/02)

Enantiomerically pure (+)-as well as (-)-aristeromycin can be synthesized starting from (+)- or (-)-butyl (or hexyl) 4-acetamido-cyclopent-2-ene carboxylate; these carboxylates are easily obtained from their corresponding racemates by hydrolysis with the lipase from Candida rugosa.
