Methyl N-(tert-butoxycarbonyl)-L-alaninate

Description:

Methyl N-(tert-butoxycarbonyl)-L-alaninate, with the CAS number 28875-17-4, is an organic compound commonly used in peptide synthesis and as a protecting group in organic chemistry. It features a methyl ester functional group, which enhances its solubility in organic solvents and facilitates reactions. The tert-butoxycarbonyl (Boc) group serves as a protective group for the amino functionality of L-alanine, allowing for selective reactions without interfering with the amine. This compound is typically a white to off-white solid and is stable under standard laboratory conditions. It is soluble in polar organic solvents like methanol and dichloromethane, making it suitable for various synthetic applications. The presence of the Boc group also contributes to the compound's stability against acidic conditions, while it can be removed under specific conditions to regenerate the free amine. Overall, Methyl N-(tert-butoxycarbonyl)-L-alaninate is a valuable intermediate in the synthesis of peptides and other complex organic molecules.

Boc-L-alanine methyl ester

CAS: 28875-17-4

Boc-L-alanine methyl ester is a pseudopeptide that is synthesized by the reaction of an amine with a carboxylic acid. This uncharged molecule has two functional groups, one of which is a lactam and the other an amine. These functional groups are used in cross-coupling reactions to produce new molecules. Boc-L-alanine methyl ester can be catalysed by magnesium and it reacts at a faster rate than its parent compound, L-alanine methyl ester. It can also be used as a ligand for nanospray experiments and has been shown to have stereoselective properties.
