Fluorinated highly functionalized cispentacin derivatives were synthetised starting from an unsaturated bicyclic β‐lactam through CC bond functionalizationvia the dipolarcycloaddition of a nitrileoxide, isoxazoline opening, and fluorination by OH/F exchange.

New isoxazoline-fused cispentacins were prepared by the 1,3-dipolar cycloaddition of nitrile oxides to beta-amino esters containing a cyclopentene skeleton. This synthetic procedure gave regio- and diastereoisomers of the cispentacins. The synthetic route was extended to the synthesis of these compounds in enantiomerically pure form.
