Synthesis of Substituted 2-Oxo-2,3-dihydro-1H-imidazo-[1,2-a]indole-6,7-dicarbonitriles
摘要:
A three-step procedure has been developed for the synthesis of 2-oxo-2,3-dihydro-1H-imidazo-[1,2-a]indole-6,7-dicarbonitriles from substituted 2-amino-1-hydroxy-1H-indole-5,6-dicarbonitriles.
Synthesis of 3-substituted 2-amino-1-hydroxy-1H-indole-5,6-dicarbonitriles
摘要:
A method of synthesizing new 3-substituted 2-amino-1-hydroxy-1H-indole-5,6-dicarbonitriles has been developed based on the reductive cyclization of substituted 4-cyanomethyl-5-nitrophthalonitriles.
