Substituted pyridines of formula (IA) are produced by reaction of suitably substituted pyridylaldehydes with Grignard or Witting reagents, and the resulting products are appropriately reduced. The pyridines of formula (IA) are suitable as active compounds in pharmaceutical products, particularly in pharmaceutical products for the inhibition of cholesterol ester transfer proteins. 3-Heteroalkyl-aryl-substituted pyridines of formula (IB) are produced from pyridines which are correspondingly protected at the hydroxy group and correspondingly substituted. The compounds of formula (IB) according to the invention are suitable as active compounds in pharmaceutical products, particularly pharmaceutical products for the treatment of hyperlipoproteinemia. Substituted pyridines and benzenes of formula (IC) are produced by procedures disclosed herein, and are useful as active ingredients in pharmaceutical products, particularly pharmaceutical products for inhibition of the glucagon receptor, leading to treatment of glucagon-mediated conditions such as diabetes.

On produit des pyridines substituées de formule (IA) en faisant réagir des pyridylaldéhydes convenablement substitués avec des réactifs de Grignard ou de Wittig, puis en réduisant de manière appropriée les produits obtenus. Les pyridines de formule (IA) conviennent comme composés actifs dans des produits pharmaceutiques, destinés notamment à l'inhibition des protéines de transfert des esters du cholestérol. On produit des pyridines 3-hétéroalkyl-aryle-substituées, de formule (IB), à partir de pyridines protégées et substituées de manière appropriée au niveau du groupe hydroxyle. Les composés de formule (IB) de l'invention conviennent comme composés actifs dans des produits pharmaceutiques, destinés notamment au traitement de l'hyperlipoprotéinémie. Des pyridines et des benzènes substitués de formule (IC), produits par des techniques exposées ici, sont utiles comme principes actifs dans des produits pharmaceutiques destinés notamment à l'inhibition des récepteurs du glucagon, qui permettent de traiter des états dont ce dernier est le médiateur, tels que le diabète.
