An easy and convenient synthesis process is reported for the synthesis of CuO nanoparticles using plant extract for use as a catalyst in the aza-Michael addition reaction.
The present invention is related to benzoxazole acetonitriles as well as to pharmaceutical formulations containing such benzoxazole acetonitriles pof formula (I). Said benzoxazole acetonitriles are useful in the treatment of metabolic disorders mediated by insulin resistance or hyperglycernia, comprising diabetes type II, inadequate glucose tolerance, insulin resistance, obesity, polycystic ovary syndrome (PCOS). The present invention is furthermore related to methods of preparing benzoxazole acetonitriles (I). A is a pyrimidinyl.L is a secondary or tertiary amino group, or a 3-8 membered heterocycloalkyl, containing at least one heteroatom. selected from N, O, S or L is an acylarnino moiety.R1 is selected from the group comprising or consisting of hydrogen, sulfonyl, amino, CiC6-alkYl, C2-C6-alkenYl, C2-C6-alkynyl or Cl-C6-alkoxy, aryl, halogen, carboxy,aminocarbonyl, cyano or hydroxy.

of mid-2017, only one structure of the human immunodeficiency virus (HIV) integrase core domain co-crystallised with an active site inhibitor was reported. In this structure (1QS4), integrase is complexed with a diketo-acid based strand-transfer inhibitor (INSTI). This structure has been a preferred platform for the structure-based design of INSTIs despite concerns relating to structural irregularities

Acrylonitrile reacts with aromatic aldehyde imines containing a hydroxy group in the β- or γ-position to give 70–85% of the corresponding 2-aryl-3-cyanoethyltetrahydro-1,3-oxazines or 2-aryl-3-cyanoethyl-1,3-oxazolidines, respectively. The results of these reactions are rationalized in terms of ring-chain isomerism of the initial imines.
