Alcohols-buliding-blocks

Adding a certain compound to certain chemical reactions, such as: 23147-58-2, Glycerol aldehyde dimer, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 23147-58-2, blongs to alcohols-buliding-blocks compound. 23147-58-2

A mixture of final compound 2 (prepared according to Bl. b) (0.001 mol, 0.5 g), 1,4- dioxane-2,5-diol (0. 001 mol, 0.113 g) and 3-thiophene boronic acid (0. 001 mol, 0.106 g) in ethanol (5 ml) was stirred at room temperature for 18 hours. This was followed by addition of solution OF KC03 (10 %) and extracted with ethyl acetate. The combined organic layers were dried (MgSO4), filtered and concentrated under vacuum. The residue (0.6 g) was purified by column chromatography over silica gel (eluent: CH2Cl2/MeOH/NH40H 93/07/0.5) and the product fractions were concentrated. Yield: 0.075 g (12 %) of final compound 349.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,23147-58-2, its application will become more common.

7287-81-2, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 7287-81-2, name is 1-(m-Tolyl)ethanol. A new synthetic method of this compound is introduced below.

General procedure: A 1,2-dichloroethane (2.0 mL) solution of alcohol 1 (0.3 mmol), enol acetate 2 (0.3 mmol), andReBr(CO)5 (5 mol%) was stirred under an atmosphere of nitrogen at 80 C for 5 h. After the reactionwas complete, H2O was added to the reaction mixture and extracted with ethyl acetate. The organiclayer was dried with MgSO4. The resulting mixture was filtered, and the filtrate was concentrated.Purification of the residue by silica gel column chromatography afforded carbonyl compounds.Further purification was carried out by recyclable preparative HPLC, if necessary. The structures ofthe products were assigned by their 1H and 13C-NMR, and mass spectra. The product was characterizedby comparing its spectral data with those of authentic sample or previous reports 3a,S1 3b,S2 3c,S2a3d,S2a,S3 3f,S4 3h,S5 3i,S6 3j,S7 3k,S4 3l,S8 3m,S9 3n,S2a 3o,S5 3q,S10 3t,S2a,S11 and 3u. S12 The structures of theproducts (3g, 3o, 3p, 3q, 3r, 3s, and 3v) were assigned by their 1H and 13C NMR, IR and mass spectra

At the same time, in my other blogs, there are other synthetic methods of this type of compound,7287-81-2, 1-(m-Tolyl)ethanol, and friends who are interested can also refer to it.
