  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.

  An efficient preparation of fused [2,1-b]quinazolinones has been developed utilizing polymer-supported reagents. (±)-Vasicinone was converted into its dione by oxidation with poly (4-vinylpyridiniumdichromate). An efficient method has been developed for the synthesis of (d)- and (l)-vasicinone via asymmetric reduction of pyrrolo[2,l-b]quinazoline-3,9-dione by employing NaBH 4 /Me 3 SiCl as the reducing

  Herein, we report a nickel‐catalyzed intramolecular dual annulation reaction of alkyl nitrile‐containing 1,2,3‐benzotriazine‐4(3H)‐ones to synthesize polycyclic quinazolinones. This catalytic reaction can construct the core structure of polycyclic quinazolinone alkaloids; therefore, we also apply this reaction as the critical step to access fifteen relevant alkaloids to demonstrate efficacy.
