Disclosed herein are peptide analogs of the luteinizing hormone releasing hormone (LH-RH) which are potent antagonist of LHRH. The analogs differ in structure from LH-RH by having different amino acid residues at positions 1, 2 and 6, and optionally at positions 3 and 10. Methods for preparing and using these analogs are described.

N-Chlorination of various amides, lactams, and carbamates with very cheap trichloroisocyanuric acid proceeds efficiently under very mild conditions. Excellent results were also observed for the N-chlorination of carbamates of free amino acids.
