  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.

  triflates catalyze the chemoselective reduction of aromatic azides to the corresponding amines in combination with sodium iodide. This mild chemoselective method has been applied to the synthesis of various aryl amines, C2‐azido‐substituted pyrrolo[2,1‐c][1,4]benzodiazepines, and fused[2,1‐b]quinazolinones by an intramolecular azido reduction tandem cyclization reaction. Interestingly, this methodology

  have been numerous reports on the synthesis of similar skeletons. We have employed the T1 triazene linker to yield 1,4-benzodiazepin-5-one. Starting from various substituted triazene resins, cleavage in the presence of an azide donor, such as trimethylsilylazide, gave rise to aryl azides. Intramolecular aza-Wittig reactions produced the appropriately functionalized N-heterocycles. By using this route

  A novel route to benzoannelated large-membered cyclic 1,5-diamines from lactams is described. Thus, n-membered lactams 1 were N-acylated by o-azidobenzoyl chloride 5 to afford the corresponding imides 4. These were treated with tributylphosphine and underwent an intramolecular aza-Wittig reaction to give n-membered ring-fused quinazolinones 2 in 84-96% yield. By reductive cleavage of 2 with BH3.THF, (n+4)-membered cyclic diamines 3 were obtained in 52-95% yield.
