  Stereoselective radical cascade approach to benzo[a]quinolizidines

  摘要：

  The treatment of enamide 15, having an (E)-4-ethoxycarbonyl-3-butenyl group on the nitrogen atom. with Bu3SnH-AIBN in boiling benzene, afforded a 1.2:1 mixture of two benzo[a] quinolizidine stereoisomers 16 and 17 as a result of cascade radical cyclization. A similar treatment of the (2)-4-ethoxycarbonyl-3-butenyl congener 19 gave 16 and 17 in a ratio of 3.4:1. The high stereoselectivity (16:17 = 37:1) from 19 was obtained using Et3B as the initiator at -78 degrees C in toluene. (C) 1999 Elsevier Science Ltd. All rights reserved.

  The present invention is directed to reactor systems and processes for producing acrylonitrile and acrylonitrile derivatives. In preferred embodiments of the present invention, the processes comprise the following steps: introducing an epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet; contacting the epoxide reagent and carbon monoxide reagent with a carbonylation catalyst to produce a beta-lactone intermediate; polymerizing the beta-lactone intermediate with an initiator in the presence of a metal cation to produce a polylactone product; heating the polylactone product under thermolysis conditions to produce an organic acid product; optionally esterifying the organic acid product to produce one or more ester products; and reacting the organic acid product and/or ester product with an ammonia reagent under ammoxidation conditions to produce an acrylonitrile product.

  本发明涉及反应器系统和生产丙烯腈及丙烯腈衍生物的工艺。在本发明的优选实施例中，该工艺包括以下步骤：将环氧试剂和一氧化碳试剂通过至少一个进料流入口引入至至少一个反应釜中；将环氧试剂和一氧化碳试剂与羰基化催化剂接触以产生β-内酯中间体；在金属阳离子存在下，将β-内酯中间体与引发剂聚合以产生聚内酯产品；在热解条件下加热聚内酯产品以产生有机酸产品；可选择酯化有机酸产品以产生一个或多个酯产品；并将有机酸产品和/或酯产品与氨试剂在氨氧化条件下反应以产生丙烯腈产品。
