use | (3S)-3-(hydroxymethyl) morpholin-4-carboxylate tert-butyl ester is a key intermediate in the synthesis of BMS-599626, BMS-599626 selective and effective oral inhibitors of human epidermal growth factor receptor 1 and 2 kinases. As an organic chemical intermediate, N-substituted morpholine has the dual properties of tertiary amine and ether, and has a wide range of applications. It can be used as a catalyst for the production of polyurethane foam. The catalyst in the synthesis process can also be used as a surfactant, extractant, corrosion inhibitor, and its derivative N-methyl morpholine oxide. It is a very ideal spinning solvent for the manufacture of Lyocell natural fibers and Newcell man-made fiber filaments. |
preparation | N-substituted morpholine contains double groups of tertiary amine and ether, which is not only an important catalyst in the foaming process of semi-synthetic penicillin and polyurethane, but also an important raw material for the synthesis of N-substituted morpholine oxide. The current synthesis process mainly includes morpholine method, N-methyl diethanolamine method, diethanolamine method, diethylene glycol method and dichloroether method. (3S)-3-(hydroxymethyl) morpholine -4-carboxylic acid tert-butyl ester is substituted with (R)-(4-benzyl-3-morpholine)-methanol as the starting material and is prepared by reacting with diptert-butyl dicarbonate. The synthesis reaction formula is as follows: Figure 1 (3S)-3-(hydroxymethyl) morpholine -4-carboxylic acid tert-butyl ester synthesis reaction experimental operation: add triethylamine to the dichloromethane solution of (R)-(4-benzyl-3-morpholine)-methanol, drop the dichloromethane solution of di-tert-butyl dicarbonate, drop it, and react for 15 hours. The solvent is distilled under reduced pressure, and the concentrate is processed by silica gel column chromatography [eluent: V (ethyl acetate) /V (petroleum ether) = 1/10] purified compound (3S)-3-(hydroxymethyl) morpholin-4-carboxylic acid tert-butyl ester. |
