Yield: 86.17%
Reaction Conditions:
with hydrogen bromide in tetrahydrofuran;1,4-dioxaneGreen chemistry;
Steps:
3.3; 4.3 Preparation of L-selenomethionine, the structural formula is as follows:
14.64g of N- Carbobenzyloxy L-selenomethionine was heated and stirred, then dropwise added 50mL of 10% HBr in 1,4-dioxane solution, after the reaction was completed, cooled to room temperature, and filtered to obtain a solid; The solid was added with 40 mL of H2O for dissolving, 2.11 g of lithium hydroxide monohydrate was added to the mixture, stirred at room temperature, then stirred with EtOH for 10 min. suction-filtered to obtain a solid which was washed with a mixture of ethanol and water, filtered, dried, and weighed to give a white solid 8.38g, total yield was 86.17%, and the HPLC content was 97.63%.
