4-AMINO-2-[(TERT-BUTOXYCARBONYL)AMINO]-4-OXOBUTANOIC ACID - Introduction
Boc-DL-Asparagine is an organic compound with the chemical structure Boc-(R)-Asparagine. It is synthesized by reacting aspartic acid with carbamate having Boc protecting group.
Boc-DL-asparagine has the following main properties:
-Appearance: a colorless or almost colorless crystalline powder;
-Molecular formula: C11H18N2O4;
-Molecular weight: 242.27g/mol;
-melting point: about 136-139 ℃;
-Solubility: Good solubility in some organic solvents, such as methanol, chloroform and dichloromethane.
Boc-DL-asparagine is commonly used in organic synthesis protecting group strategy, can protect the amino and carboxyl functional groups of aspartic acid, in order to avoid unnecessary reactions in the synthesis process. After completion of the desired reaction, the Boc group can be removed by deprotection under appropriate conditions, such as acid-catalyzed or fluorinated deprotection, to obtain the original aspartic acid.
Boc-DL-asparagine applications include:
-Protecting group strategy in organic synthesis;
-Synthesis of intermediates in drug development;
-Synthesis of derivatives of natural products.
However, please note the following safety information:
