  Homobivalent Quinazolinimines as Novel Nanomolar Inhibitors of Cholinesterases with Dirigible Selectivity toward Butyrylcholinesterase

  摘要：

  Homobivalent dimers of quinazolinimines, which bridge the imine nitrogen atoms via a hepta-and an octamethylene spacer, with different ring sizes of the alicycles were synthesized from the corresponding quinazolinethiones. The resulting compounds show > 100-fold increase of inhibitory activities compared to related monomeric compounds yielding low-nanomolar inhibitors. For heptamethylene dimers, mixed inhibition profiles were obtained, whereas for the octamethylene compounds selectivity toward butyrylcholinesterase (> 180) can be achieved with an eight-membered alicycle.

  Chemoenzymatic Synthesis of Pyrrolo[2,1-b]quinazolinones:  Lipase-Catalyzed Resolution of Vasicinone

  摘要：

  A facile synthesis of bronchodilatory pyrrolo [2,1-b] quinazoline alkaloids by azidoreductive cyclization strategy employing TMSCl-NaI and bakers' yeast is described. Both the chemical and enzymatic methods are mild and take place at room temperature in good yields. Further, synthesis and resolution of vasicinone has been carried out by employing different lipases. It has been observed that lipase PS provides acetate of (S)-vasicinone in 98% ee.

  inexpensive method using microwave-assisted irradiation with Ni2B for the syntheses of aromatic amines, pyrrolobenzodiazepines as well as pyrroloquinazolinones was developed. This protocol was applied in the tandem resin-cleavage, azido reduction, and cyclization of compounds 3 and 5 that afforded substituted pyrrolo[2,1-c][1,4]benzodiazepines 4 and 6 in a one-pot manner.
