79990-15-1 - Reference Information
| Introduction | Fmoc-D-alanine is white or off-white solid at normal temperature and pressure, it is a commercial amino acid organic Synthon, which is generally soluble in N,N-dimethylformamide, dimethyl sulfoxide and alcohol solvents, and has poor solubility in water, and can be used as an intermediate in organic synthesis. |
| uses | Fmoc-D-alanine is a common amino acid class of organic synthons. The most common application is to convert the carboxyl group into an acid chloride, and then to link the molecular fragment carried by the amino acid to the target molecule by synthesizing an amide or ester compound. In addition, carboxyl groups can also be converted into active functional groups such as hydroxyl groups and aldehyde groups. |
| synthesis method | for the synthesis of Fmoc-D-alanine, the conventional synthesis method is based on D-alanine, the target product is obtained by an amine transesterification reaction with an ester of a precursor compound. In general, the reaction requires the addition of a small amount of a weak base to promote the reaction, and needs to be carried out at a high temperature. |
