A practical synthesis of LFA-1 inhibitors utilizing CuCl-promoted intramolecular cyclization of thiohydantoins

An efficient and chromatography-free approach for synthesis of a new class of LFA-1 inhibitors was developed. A copper(I) chloride-promoted intramolecular cyclization of thiohydantoins 7a-b serves as a key step to highly functionalized bicyclic guanidines

A practical synthesis of highly functionalized fused 1,6-dihydroimidazo-[1, 2-a]imidazole-2,5-diones, key intermediates for LFA-1 inhibitors

An alternative and chromatography-free approach for synthesis of a new class of LFA-1 inhibitors was developed. A key feature of this process involved a transformation of thioureas 14 to acyclic guanidine derivatives 9 followed by intramolecular cyclizati
