Method:
t-Boc-N-Amido-PEG3-propargyl synthesis methods are more diverse, but a common synthetic route is as follows:
1. Esterification of N-tert-butoxycarbonylidenetrimethylalanine tert-butyl ester with activated polyethylene glycol (PEG) to form a hydrophilic segment of PEG protected by N-acyl.
2. Through the nucleophilic substitution reaction, the tert-butoxycarbonyl subunit is converted into the tert-butoxycarbonyl (Boc) group of the protected amino acid.
3. The propyne functional group is introduced into the hydrophilic segment of PEG. The method can be nucleophilic substitution reaction or electrophilic substitution reaction.
4. Finally, the t-Boc-N-Amido-PEG3-propargyl is obtained through appropriate separation and purification processes.
Safety Information:
t-Boc-N-Amido-PEG3-propargyl are chemical reagents that need to be used and stored correctly to ensure safety. Observe the following safety measures:
-Avoid direct contact with skin, eyes and mucous membranes. Wear appropriate personal protective equipment such as lab gloves and goggles when using.
