A chiral cyclopentadienyl-rhodium(III) catalyzedhighly enantioselective aziridination of challenging unactivatedterminalalkenes and N-pivalolyloxy sulfonamides has been developed. This catalytic system demonstrated outstanding catalytic activity and broad functional group tolerance, yielding synthetically important and highly valuable chiral aziridines with good to excellent yields and enantioselectivities

The present disclosure provides compounds having the general structure A or pharmaceutically acceptable salts thereof:
R—X (A)
wherein R is an alkyl or aryl moiety comprising heterocyclic structures; and X is a metal-chelatin group selected from:
This disclosure further provides a focused library of compounds for use in the discovery and design of metallo-enzyme inhibitors. This fragment-based approach provides an assembly of a library of low molecular weight compounds (MW<300 Da) containing a variety of potential metal-chelating groups. The identification of the inhibitory scaffolds among these compounds provides the initial hit fragments that may be optimized for affinity against a particular target using common medicinal chemistry, structure-based or NMR-based approaches.
