Preparation method of AEEA
-
Paragraph 0067-0069, (2021/10/27)
The invention relates to the technical field of chemical synthesis, in particular to a preparation method of AEA. According to the preparation method of AEEA provided by the invention, amino on diglycol amine is protected by chloroacetyl chloride, then ring formation is carried out in the presence of NaH, and AEEA is obtained through hydrolysis. The method has the advantages of reduced reaction steps, low production cost, high product purity and few impurities, and is suitable for industrial large-scale production.
Preparation method of [2-[1-(Fmoc-amino)ethoxy]ethoxy]acetic acid

Paragraph 0065; 0068; 0070, (2019/09/17)
The invention provides a preparation method of [2-[1-(Fmoc-amino)ethoxy]ethoxy]acetic acid. The preparation method comprises steps as follows: amino protection is performed on diglycolamine by use ofphthalic anhydride, an obtained intermediate and halo-acetic acid or halo-acetate are subjected to a reaction, deprotection or deprotection and hydrolysis are performed, a product reacts with a Fmoc-based amino protection reagent, and [2-[1-(Fmoc-amino)ethoxy]ethoxy]acetic acid is obtained. In the preparation method, phthalic anhydride and diglycolamine are taken as initial raw materials, short time is required by an amino protection reaction, an obtained intermediate compound has good stability, can be preserved for a long time and does not react with water, water-soluble impurities (such asthe raw material diglycolamine, a byproduct phthalic acid and the like) can be separated through extraction, so that an amino protection product with high purity is obtained, and the purity and the yield of the target product are also improved.

Herein, we report the facile preparation of cell-targeted platinum nanoparticles (PtNPs), through the design of peptides that, as a single molecule added in small concentration during the synthesis, control the size of PtNP clusters during their growth, stabilise the PtNPs in aqueous suspension and enable the functionalisation of the PtNPs with a versatile range of cell-targeting ligands. Water-soluble PtNPs targeted respectively at blood group antigens and at integrin receptors are demonstrated.
