  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. The microwave-assisted irradiation

  An efficient method for the reduction of aromatic azides in both solution and solid-phase has been developed by employing (BF3OEt2)-O-./EtSH. This report also describes resin cleavage employing this reagent system. Further, this protocol has been utilized for the solution as well as the solid-phase synthesis of pyrrolo[2, 1-c][1,4]benzodiazepines, including the naturally occurring antibiotic DC-81 and fused [2,1-b]quinazolinones.
