Synthesis of tricyclic-2-aminoindoles by intramolecular 1,3-dipolar cycloaddition of 1-ω-azidoalkylindoles
摘要:
Thermolysis of the 1-omega -azidoalkylindoles 4, bearing an electron attracting substituent at C-3 (CHO, COMe, COOMe, CN) provides imidazo[1,2-a]indoles (5, n = 1), pyrimidino[1,2-a]indoles (5, n = 2), and 1,3-diazepino[1,2-a]indoles (5, n = 3). (C) 2001 Elsevier Science Ltd. All rights reserved.
