A novel synthesis of 3,4-disubstituted cinnolines from o-trifluorophenyl hydrazones
摘要:
An efficient synthesis of 3-aryl-4-aminocinnolines from ortho-trifluoromethylphenyl hydrazones is described. The mechanism of the described transformation is likely to involve the formation of the quinone methide intermediate. The described procedure is easily adaptable to automated solid phase synthesis leading to analytically pure heterocycles. (C) 1999 Elsevier Science Ltd. All rights reserved.
