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

Disclosed is a 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. As a res

DERIVATIVES OF 6,7-DIHYDRO-5H-IMIDAZO[1,2-a] IMIDAZOLE-3-SULFONIC ACID

Derivatives of 6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-sulfonic acid which exhibit good inhibitory effect upon the interaction of CAMs and Leukointegrins and are thus useful in the treatment of inflammatory disease.

Development of a scalable process for 1-(3,5-dichlorophenyl)-5-iodo-3- methyl-(4-methylbenzyl)-1H-imidazo[1,2-a]imidazol-2-one: A key intermediate for the synthesis of LFA-1 inhibitors

A safe, robust, chromatography-free and reproducible process for the multi-kilogram synthesis of vinyl iodide 2, a key intermediate for the synthesis of LFA-1 inhibitors, was developed and implemented at the pilot plant. Execution of the above process all

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

Second-generation lymphocyte function-associated antigen-1 inhibitors: 1H-imidazo[1,2-α]imidazol-2-one derivatives

A novel class of lymphocyte function-associated antigen-1 (LFA-1) inhibitors is described. Discovered during the process to improve the physicochemical and metabolic properties of BIRT377 (1, Figure 1), a previously reported hydantoin-based LFA-1 inhibito

DERIVATIVES OF [6,7-DIHYDRO-5H-IMIDAZO[1,2-a]IMIDAZOLE-3-SULFONYLAMINO]-PROPIONAMIDE

Derivatives of [6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-sulfonylamino]-propionamide which exhibit good inhibitory effect upon the interaction of CAMs and Leukointegrins and are thus useful in the treatment of inflammatory disease.

Regiocontrolled synthesis of highly-functionalized fused imidazoles: A novel synthesis of second generation LFA-1 inhibitors

A new and reliable route to a new class of LFA-1 inhibitors such as (2) has been developed. A key aspect of this route is the transformation of amino amide 5 into iodide 3 in four steps. Iodide 3 is a key advanced intermediate used in the synthesis of all
