In 2019,Synlett included an article by Kandula, Venu; Thota, Pradeep Kumar; Mallesham, Poosa; Raghavulu, K.; Chatterjee, Anindita; Yennam, Satyanarayana; Behera, Manoranjan. Synthetic Route of C5H13NO2. The article was titled 《Selectfluor-Mediated Tandem Cyclization of Enaminones for the Synthesis of 3-Fluorochromones》. The information in the text is summarized as follows:
An efficient synthesis of various 3-fluorochromones (3-fluoro-4H-chromene-4-ones) from enamino ketones by using Selectfluor was described. The key step in the synthesis involves tandem fluorination and cyclization to form 3-fluorochromones in good yields. The significant features of this method include simple operational procedures, a high purity of the product and excellent regioselectivity. In the part of experimental materials, we found many familiar compounds, such as N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Synthetic Route of C5H13NO2)
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Synthetic Route of C5H13NO2
