| Abstract: | Cycloalkanone oximes react with C-(2-furoyl)-, C-(2-thenoyl)- and C-(phenylaminocarbonyl)nitrile imines to give unexpected 3-substituted 1-aryl-1,2,4-triazaspiroalk-2-enes rather than the cycloaddition or the cyclocondensation products.For Part 3 see Ref. 1.Published in Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1626–1631, November, 2004. |
