α-Methyl and alkyl-amino acids can be produced by a number of platforms, where the (2S,4S)-4-methyl-2-phenyloxazolidin-5-one scaffold is one of the most popular one. We optimize published procedures and have own proprietary ones, which enable us to supply all kinds of protected α-methyl amino acids.
Such building blocks are being used to build up resistance towards proteolytic digestion of corresponding peptides or to implement certain amid bind conformation.
An alternative are β,β-dimethylated amino acids, where structure of the α-carbon is being maintained and the stability providing property comes through derivatization at the neighbouring carbon.
With tert-leucine and penicillamine there are already derivatives known in the peptide community, however, access to other analogues is very unique and available only through our specific synthesis platform.
