Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. 121-89-1, Name is 3′-Nitroacetophenone, molecular formula is C8H7NO3, Safety of 3′-Nitroacetophenone, belongs to isothiazole compound, is a common compound. In a patnet, author is BAGGI, P, once mentioned the new application about 121-89-1.
3-Diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide(3) readily reacts with oxazolones 2 and munchnones 7 affording with satisfactory yield 3-diethylamino-4,6-diaryl-3a,4-dihydro-3a-(4-methoxyphenyl)6aH-pyrrolo[3,4-d]isthiazole 1,1-dioxides 4 and 3-diethylamino-4,6-diaryl-5-alkyl-3a-(4-methoxyphenyl)-pyrrolo[3,4]isothiazole l,1-dioxides 8, respectively. The behaviour of the cycloadducts towards elevated temperatures and/or basic conditions was investigated. Under these conditions the primary products lost SO2 and diethylcyanamide affording 1-alkyl-2,3,5-triarylpyrroles 9 and 1H-2,3,5-triarylpyrroles 10. These latter were found to be better obtained through thermal decomposition of N-protected cycloadducts 8 and subsequent deprotecting the final pyrroles.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 121-89-1. Safety of 3′-Nitroacetophenone.
