38585-74-9, Name is Thiazol-5-ylmethanol, molecular formula is C4H5NOS, belongs to thiazole compound, is a common compound. In a patnet, once mentioned the new application about 38585-74-9, HPLC of Formula: C4H5NOS

Photoirradiation of 2-arylthiazoles derivatives linked with an alkene moiety through a three-atom spacer was investigated. The main products were unexpected tetrahydrofuran-fused thiazepine derivatives with concomitant formation of [2+2] cycloaddition products and regioisomeric thiazoles. The product distribution was little influenced by the reaction conditions and substituents of the substrates.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 38585-74-9, Name is Thiazol-5-ylmethanol, Computed Properties of C4H5NOS.

A study on the use of derivatized carbohydrates as C2-symmetric HIV-1 protease inhibitors has been undertaken. L-Mannaric acid (6) was bis-O- benzylated at C-2 and C-5 and subsequently coupled with amino acids and amines to give C2-symmetric products based on C-terminal duplication. Potent HIV protease inhibitors, 28 K(i) = 0.4 nM and 43 K(i) = 0.2 nM, have been discovered, and two synthetic methodologies have been developed, one whereby these inhibitors can be prepared in just three chemical steps from commercially available materials. A remarkable increase in potency going from IC50 = 5000 nM (23) to IC50 = 15 nM (28) was observed upon exchanging – COOMe for -CONHMe in the inhibitor, resulting in the net addition of one hydrogen bond interaction between each of the two -NH- groups and the HIV protease backbone (Gly 48/148). The X-ray crystal structures of 43 and of 48 have been determined (Figures 5 and 6), revealing the binding mode of these inhibitors which will aid further design.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.38585-74-9, Name is Thiazol-5-ylmethanol, molecular formula is C4H5NOS. In a Patent£¬once mentioned of 38585-74-9, Recommanded Product: Thiazol-5-ylmethanol

A process for the preparation of 5-hydroxymethylthiazole comprises reacting a compound of the formula, STR1 with a carboxylic acid salt (optimally in the presence of a quaternary ammonium salt) and hydrolyzing the resulting ester. Subsequent dechlorination gives 5-hydroxymethylthiazole.

REFERENCE EXAMPLE 50 2-Fluoro-4-(thiazol-5-ylmethoxy)benzonitrile Diisopropylazodicarboxylate (4.0 g) was dissolved in a little anhydrous tetrahydrofuran (about 10 ml) and added dropwise to a stirred solution of triphenylphosphine (5.2 g) in anhydrous tetrahydrofuran (150 ml) at 0 C. under nitrogen. After stirring at 0 C. for 15 minutes, during which time a white precipitate formed, a mixture of 2-fluoro-4-hydroxybenzonitrile (S. M. Kelly, Helv.Chim.Acta. 1984, Volume 67, P.1572-1579) (2.0 g) and thiazole-5-methanol (2.3 g) in anhydrous tetrahydrofuran (20 ml) was added dropwise whilst maintaining the temperature at or below 5 C. The reaction mixture was stirred in the cooling bath for a further 2 hours then allowed to warm slowly to room temperature. After standing at room temperature overnight the reaction mixture was partitioned between ethyl acetate (200 ml) and saturated aqueous ammonium chloride solution (200 ml). The layers were separated and the organic phase washed with water (100 ml), dried over magnesium sulphate and evaporated. The residue was purified by flash chromatography on silica eluding with a mixture of ethyl acetate and cyclohexane (1:1, v/v). Fractions homogenous in the required product were combined and evaporated affording the title compound as a pale yellow solid (2.0 g).

After being stirred for 1 h, the reaction mixture was diluted with CHCl3, washed successively with 1N HCl, saturated aqueous NaHCO3, and saturated brine, dried over NaSO4, and concentrated in vacuo. The residue was purified by silica gel chromatography (SiO2, 1-2% MeOH/CHCl3, Rf=0.5 in 4% MeOH/CHCl3) to yield 5.9 g (78%) of the desired compound as a yellow solid.
