The present invention relates to novel heterocyclically fused diaryldihydropyrimidine derivatives, to processes for their preparation, to their use alone or in combination for the treatment and/or prevention of diseases and also to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of disorders of the lung and the cardiovascular system.
A new protocol for the Knoevenagel condensation between β-diketones and aliphatic and aromatic aldehydes promoted by Mg(ClO4)2 under mild conditions is reported.
The invention relates to novel dihydropyridinone derivatives, processes for their preparation, and their use in medicaments, especially for the treatment of chronic obstructive pulmonary diseases, acute coronary syndrome, acute myocardial infarction and heart failure development.

Addition of alpha-arylmethylidene- or alpha-alkylidene-beta-keto ester enolate to N-activated aldimines via the imino aldol pathway followed by intramolecular aza-Michael reaction in a domino fashion has been developed, and a highly diastereoselective route to substituted piperidines is reported. Enantiopure piperidines are synthesized from chiral sulfinyl imines. Formation and the observed stereoselectivity of the products have been rationalized by mechanistic and computational studies.
