Synthesis of 6,7-Dihydro-5H-imidazo[1,2-a]imidazole-3-sulfonic acid amides

Disclosed is an improved multi-step process for preparing a compound of Formula I: wherein R1 to R3 are as defined herein. The compounds of formula I inhibit the binding of human intercellular adhesion molecules to the Leukointegrins

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
