Stereo- and regiocontrolled synthesis of highly functionalized cyclopentanes with multiple chiral centers

The synthesis of some highly substituted three-dimensional cyclopentanes with multiple chiral centers and with high regiochemical and stereochemical diversity has been accomplished starting from cyclopentadiene-derived aminocyclopentenecarboxylic acids. The small-molecular design consisted of stereo- and regiocontrolled functionalization of the starting cyclopentene β- and γ-amino acids through oxirane formation/oxirane opening and afforded regio- and diastereoisomers of orthogonally protected aminocyclopentanecarboxylates.

Enantiomerically pure alkyl (1S,4R)- and (1R,4S)-4-acetamido-cyclopent-2-ene-carboxylates are obtained from their corresponding racemates by hydrolysis with PLE or the lipase from Candida cylindracea.
