use
1, used for polypeptide synthesis, used as amino acid protection monomer.
2. Organic intermediates.
3. Biochemical studies
4, for the synthesis of biochemical reagents, diazepam, fludiazepam, chlorprazolam mesylate and other peptides.
5, used as polypeptide reagent
production method
1. Under cooling, add benzyl chloroformate and sodium hydroxide solution dropwise to the mixture of glycine and sodium hydroxide solution while stirring vigorously. After the reaction, let it stand and separate the oil layer. The water layer is extracted with ether and then cooled and acidified to Congo red acid, the precipitate is filtered, washed and dried to obtain the product benzyloxycarbonylglycine. Yield 86-91%.
2. using benzyloxycarbonyl azide and glycine as raw materials, crude products are obtained by reaction under alkaline conditions, and then pure products are obtained by ether extraction and recrystallization.
