Boc-L-alanine benzylester

Description:
Boc-L-alanine benzylester is a novel fluorescent crosslinker that can be used to synthesize fluorescent polymers. It is composed of an acid moiety and benzothiadiazole moieties, which are catalytic. The synthesis of Boc-L-alanine benzylester involves the reaction of lysine or tyrosine with an acid chloride to form an amide bond, followed by a ring opening reaction with the corresponding benzothiadiazole. The fluorescein group is then added as a substituent at the N-terminus. This new crosslinker has been shown to have high reactivity in cycloadditions and crosslinking reactions with anthracene, cyclopentadiene, and cyclohexadiene. Boc-L-alanine benzylester has also been shown to be effective in ascorbate oxidation.
