An efficient microwave-assisted solvent-free synthesis of pyrido-fused ring systems applying the tert-amino effect
摘要:
Significant improvements in the synthesis of pyrido-fused heterocycles were observed when performing the reaction under solvent-free conditions, applying the tert-amino effect as the key ring closure methodology. An unexpected cyclization of ortho-(1'-azacycloalkyl)benzaldehydes has been studied in water and on solid support. (c) 2005 Elsevier Ltd. All rights reserved.

2-Dialkylamino-arylidene-imidazolones undergo intermolecular tandem [1,5]-hydride shift and cyclization to form spirocyclic tetrahydroquinoline derivatives under TiCl4 promotion. Different substitutions on each of the aryl, amino and imidazole fragments are tolerated, which results in 20+ examples and 25–95% yields.

The present invention provides novel compounds of formula (I) that are modulators of RORgamma. These compounds, and pharmaceutical compositions comprising the same, are suitable means for treating any disease wherein the modulation of RORgamma has therapeutic effects, for instance in autoimmune diseases, autoimmune-related diseases, inflammatory diseases, fibrotic diseases, or cholestatic diseases.
