biologically active. This work aims at the preparation of a useful synthon for total synthesis containing orthogonally protected amines. To this end, furfural and two amines were employed to form mixed trans-4,5-diaminocyclopentenones promoted by Cu(OTf)2. The selected amines can be orthogonally deprotected, allowing selective modification of the amines on the cyclopentane core. Their utility was showcased
