New and higher yielding synthetic routes to N-protected N-methylpyrrole and N-methylimidazole amino acids are introduced to circumvent difficulties associated with established schemes. Key steps in each synthesis include copper-mediated cross-coupling reaction to directly install a carbamate-protected 4-amine in the N-methylpyrrole derivative and effective nitration followed by a one-pot reduction/Boc protection of the amine in the synthesis of the N-Me-imidazole amino acid.

, (2008/06/13)
The present invention is directed to protected amino acid halide monomers and oligomers, and to their use in the efficient sythesis of polyamides. The present invention is further directed to the use of α-haloenamine reagents, which may optionally be immobilized, for the preparation of the amino acid halides.
