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. 92-70-6, Name is 3-Hydroxy-2-naphthoic acid, molecular formula is C11H8O3, Application In Synthesis of 3-Hydroxy-2-naphthoic acid, belongs to naphthyridine compound, is a common compound. In a patnet, author is Li, Chunmei, once mentioned the new application about 92-70-6.
An efficient and highly eco-friendly approach to poly-substituted 1,6-naphthyridine derivatives with good to excellent yield has been reported using simple and readily available 4-aminopyridinone, aromatic aldehyde or isatin, and 1,3-cyclohexanedione as substrates. The method features low-cost and readily accessible starting materials, green ultrasonic irradiation in water, recycle heterogeneous solid acid catalyst, broad substrate scope as well as simple one-pot operation make this strategy highly attractive. Mechanistic studies indicate that this transformation involves Knoevenagel condensation, Michael addition, and cyclization sequence. (C) 2020 Elsevier Ltd. All rights reserved.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 92-70-6. The above is the message from the blog manager. Application In Synthesis of 3-Hydroxy-2-naphthoic acid.
