  摘要：

  Twenty eight pyrrolo[1,2-a]quinoxalines bearing at position 4 various substituents related to the moieties present in classical and non classical antifolic agents were prepared and evaluated in vitro for antiproliferative activity. In an in vitro screening performed at NCI, several compounds emerged as potent antiproliferative agents at concentrations ranging between 10 and 100 microM. Interestingly, some of these compounds proved active also against bovine and murine DHFR (Farmaco 53 (1998) 480). More recently, a compound of classical antifolate type has been reported to be a potent inhibitor of hDHFR in vitro (Farmaco 58 (2003) 51). We then synthesized new derivatives that, in our hands, were endowed with in vitro antiproliferative activities as low as 3.4 microM against a panel of cell lines derived from hematological and solid tumours. In addition, a complete screening of cytotoxicity, antiretroviral HIV-1 and antimicrobial activity has been carried out.

  吲哚/吡咯并二氮平和喹喔啉的催化剂控制的化学发散环

  摘要：

  在邻吲哚苯胺和重氮化合物之间进行催化剂控制的化学发散环化反应已被研究用于合成吲哚稠合的二氮杂and和喹喔啉。在Rh（III）催化剂下，反应通过游离胺辅助的C2-H活化进行，然后进行酰胺化反应，从而以高度选择性的方式生成重氮庚并[1,7- a ]吲哚。当使用Ru（II）催化剂时，反应涉及形成Ru-卡宾配合物，然后插入-NH 2基团，并通过金属茂型反应进行级联环化，通过β-氢化物消除作用制得吲哚[1,2- a]。以喹喔啉为主要产品。该策略指导模块化方法构建独特的吲哚并结合的二氮杂/喹喔啉以及吡咯并并的二氮杂/喹喔啉骨架，并具有极高的产率。

  A ruthenium-catalyzed [5+1] annulation of 1-(2-aminophenyl)pyrroles with α-carbonyl sulfoxonium ylides is reported. This reaction provides a one-step method for synthesizing pyrrolo[1,2-a]quinoxaline derivatives under ambient conditions. The system proceeds with a short reaction time and a high functional-group tolerance. Notably, this divergent protocol tolerates β-keto sulfoxonium ylides and can
