A highly efficient and convenient one-pot sonochem. synthetic strategy has been sophisticated for synthesizing a novel class of polysubstituted pyrazolo[1,5-a]pyridines via [3 + 2] cycloaddition of dialkyl acetylenedicarboxylates, Et propiolate, and alkenes to 2-imino-1H-pyridin-1-amines under catalyst-free conditions. A series of uniquely substituted pyrazolo[1,5-a]pyridines has been synthesized with a very good to excellent yield, and the mechanistic pathway that involves a [3 + 2] annulation process was also proposed. In this study, several spectroscopic tools of analyses were employed for structure elucidation, and the X-ray single-crystal technique was utilized to confirm the proposed mechanism and the regioselectivity.N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5HPLC of Formula: 4637-24-5) was used in this study.
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.HPLC of Formula: 4637-24-5
