  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.

  Sodium iodide in acidic media has been employed for the synthesis of N-arylformamides and N-arylacetamides. The NaI/acetic acid reagent system has also been extended for the synthesis of 1,4-benzodiazepine-2,5-diones, pyrrolo[2,1-c][1,4]benzodiazepine-5,11-diones, and fused [2,1-b]quinazolinones.

  A fluorous linker-assisted synthetic protocol has been developed for preparation of sclerotigenin-type benzodiazepine-quinazolinone library containing 144 analogues. Amide coupling of fluorous trimethoxybenzyl (TMB)-protected amino esters with anthranilic acids followed by base-promoted cyclizations afforded 4-benzodiazepine-2,5-diones. Further derivatization of benzodiazepinediones by reacting with azidobenzoyl chlorides, cyclization, and fluorous linker cleavage afforded the desired compound library. The reaction intermediates were purified by fluorous solid-phase extraction (F-SPE) and final products were further purified by prep-HPLC.
