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

Practical synthesis of a cell adhesion inhibitor by self-regeneration of stereocenters

An efficient enantiospecific synthesis of the cell adhesion inhibitor BIRT-377 by self-regeneration of stereocenters has been achieved in 38% overall yield in eight steps. The key transformations involve the stereoselective formation of the trans imidazol

An improved synthesis of N-aryl-hydantoin LFA-1 antagonists via the enantiospecific alkylation of an isobutyraldehyde-derived imidazolidinone template

An improved and cost-effective process for the synthesis of N-aryl-hydantoin LFA-1 antagonists is described. Key transformations include the synthesis and stereospecific alkylation of the trans-isobutyraldehyde-derived template 4, and the one-pot hydrolys

Self-regeneration of stereocenters: A practical enantiospecific synthesis of LFA-1 antagonist BIRT-377

An efficient enantiospecific synthesis of the LFA-1 antagonist BIRT-377 has been achieved in 43percent overall yield in eight steps. The key transformations involve the stereospecific formation of the trans imidazolidinone 7, subsequent alkylation, and th
