Promoted by SmI2, 3-aryl-2,1-benzi- soxazoles underwent reductive cleavage of the NO bond leading to 2-aminobenzophenones in high yields upon protonation. Otherwise, if ketones with active methylene group were added to the reaction mixture prior to protonation, the desired polysubstituted quinolines could be obtained under mild conditions in a one-pot manner. © 2005 Wiley Periodicals, Inc.

在 SmI2 的促进下,3-芳基-2,1-苯并-恶唑经历 NO 键的还原裂解,在质子化时以高产率生成 2-氨基二苯甲酮。否则,如果在质子化之前将具有活性亚甲基的酮加入反应混合物中,则可以在温和条件下以一锅法获得所需的多取代喹啉。© 2005 Wiley Periodicals, Inc. 杂原子化学 16:637–643, 2005; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20164
