Abstract

A novel substrate-directed synthetic route to a series of highly functionalized, orthogonally protected dior triaminocyclopentanecarboxylate derivatives with multiple chiral centres from an unsaturated bicyclic b-lactam has been accomplished by applying stereoselective ring CeC double bond aziridination with chloramine-T and phenyltrimethylammonium tribromide, followed by regioselective aziridine opening with different N,O nucleophiles and hydrides. The functionalization strategy was successfully extended for access to enantiomerically pure orthogonally protected triaminocarboxylates.
