New possibilities of 1,2,4-triazines functionalization: first examples of synthesis and structure of boron-containing 1,2,4-triazines
摘要:
By oxidation of 3-thioderivatives of 1,2,4-triazine 1a,b 3-alkylsulfonic derivatives 2a,b were obtained. Interaction of the sulfonic derivative 2a with indole leads to 3-oxo-5-indolyl-5-phenyl-as-triazine 4. The sulfone 2a reacts with 1-ethyl-2,6-dimethylquinolinium iodide to give 3-(1-ethyl-6-methyl-1,2-dihydroquinoline-2-methylene)-5-phenyl-1,2,4-triazine 5. The 3-morpholino- 3 and 3-thioderivatives 6, 7a,b of as-triazine were obtained by interaction of the sulfone 2 with morpholine and organic boron-containing thiols. The crystal structure of boron-containing derivative of as-triazine 7b was investigated by X-ray analysis. (C) 2004 Elsevier Ltd. All rights reserved.
