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.
Efficient synthesis of (5-oxo-6,7-dihydro-4H-[1,2,4]triazolo-[1,5-a]pyrimidin-6-yl)acetanilides based on the recyclization of N-arylitaconimides with 3-amino[1,2,4]triazoles

A convenient method for the synthesis of 2-(2-R-5-oxo-6,7-dihydro-4H-[1,2,4]triazolo-[1,5-a]pyrimidin-6-yl)acetanilides based on the regioselective domino reaction of N-arylitaconimides with substituted 3-aminotriazoles was proposed. Presumably, the reaction pathway includes the conjugated aza-addition of the endo-nucleophilic center of triazole to imide, followed by the recyclization of the intermediate
合成2-(2-R-5-oxo-6,7-dihydro-4 H- [1,2,4] triazolo- [1,5 - a ]嘧啶-6-基)乙酰苯胺的简便方法提出了基于N-芳基衣康酰亚胺与取代的3-氨基三唑的区域选择性多米诺反应的方法。据推测,反应途径包括三唑的亲核中心与酰亚胺的氮杂加成共轭,然后将中间体环化成三唑并[1,5- a ]嘧啶。
