A Facile, Inexpensive and Scalable Route to Thiol-Protected α-Methyl Cysteine
摘要:
A facile, scalable synthesis of alpha-methyl cysteine with three alternate thiol protecting groups (trityl, allyl and tert-butyl) is described. The thiol-protected amino acids are obtained in six steps from L-cysteine ethyl ester and are ideally suited for a range of natural product and solid-phase peptide synthesis applications.
