2-Oxo-2-polyfluoroalkylethane-1-sulfones and -sulfamides in the Biginelli and ‘retro-Biginelli’ reactions
摘要:
2-Oxo-2-polyfluoroalkylethane-1-sulfones and -sulfamides react with aryl aldehydes and urea under Biginelli reaction conditions to yield 4-hydroxy-4-polyfluoroalky1-5-sulfony1-6-aryl-tetrahydropyrimidinones. The latter compounds on reaction with hexamethylenetetramine (HMTA) under thermal conditions undergo 'retro-Biginelli' reaction involving replacement of the 6-aryl substituent of the pyrimidinone cycle with a hydrogen atom donated by HMTA. Hexamethylenetetramine was employed for the first time in place of formaldehyde in the reported one-step Biginelli protocol for the synthesis of fluorinated sulfonyl-containing 6-unsubstituted tetrahydropyrimidinones.

The present invention provides novel triazole derivatives as ghrelin analogue ligands of growth hormone secretagogue receptors according to formula (I) that are useful in the treatment or prophylaxis of physiological and/or pathophysiological conditions in mammals, preferably humans, that are mediated by GHS receptors. The present invention further provides GHS receptor antagonists and agonists that can be used for modulation of these receptors and are useful for treating above conditions, in particular growth retardation, cachexia, short-, medium- and/or long term regulation of energy balance; short-, medium- and/or long term regulation (stimulation and/or inhibition) of food intake; adipogenesis, adiposity and/or obesity; body weight gain and/or reduction; diabetes, diabetes type I, diabetes type II, tumor cell proliferation; inflammation, inflammatory effects, gastric postoperative ileus, postoperative ileus and/or gastrectomy (ghrelin replacement therapy).
