    • Initial reaction of urea 4 with diketene via the secondary nitrogen, would lead to the formation of N-1H-3-(2,6-difluorobenzyl)-6-methyluracil (a regioisomer of 6). Formation of this product was never observed. The identity of 6 was confirmed by NOE NMR experiments, as outlined in Ref. d

    • note
    • Based on a docking study using a GnRH homology model obtained from the crystal structure of b-rhodopsin, we speculate that the C-5 substituent (of the uracil core) sits close to the extracellular surface of the receptor between TM domains 4 and 5. Unpublished results
