Kharaneko, A. O. published the artcileSynthesis and Modification of Hetero-Fused Pyrazoles Derived from Methyl 1-(2-Oxo-2-phenylethyl)-3-phenyl-1H-pyrazole-5-carboxylate, Application In Synthesis of 123-39-7, the main research area is hetero fused pyrazole preparation.
A modified procedure has been proposed for the synthesis of 2,7-diphenyl-5,8-dihydro-4H-pyrazolo[5,1-d][1,2,5]triazepin-4-one, and the possibility of transformation of the latter to the pyrazolo[1,5-a]pyrazine system has been demonstrated. Functionalization of 2,7-diphenyl-5,8-dihydro-4H-pyrazolo[5,1-d][1,2,5]triazepin-4-one at the 4-position and fusion of a tetrazole or triazole ring at the C4-N5 bond have been performed.
Russian Journal of Organic Chemistry published new progress about Heterocyclization. 123-39-7 belongs to class amides-buliding-blocks, name is N-Methylformamide, and the molecular formula is C2H5NO, Application In Synthesis of 123-39-7.
