Chemical Research Letters, April 2021. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 552-63-6, Name is 3-Hydroxy-2-phenylpropanoic acid, molecular formula is C9H10O3, Safety of 3-Hydroxy-2-phenylpropanoic acid, belongs to isothiazole compound, is a common compound. In a patnet, author is BAGGI, P, once mentioned the new application about 552-63-6.
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.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 552-63-6, Product Details of 552-63-6.
