合成路线1
该中间体在本合成路线中的序号：(X)The synthesis of ganirelix was performed using usual solid-state peptide synthesis with a Beckman 990 or a 5.0 L Vega 296 automated solid-phase peptide synthesizer. The synthesis was initiated by condensation of chloromethylated polystyrene/divinylbenzene resin (Merrifieled resin) (II) with Boc-D-alanine (I) by means of cesium carbonate, giving Boc-D-ala-RESIN (III), which was submitted to successive cycles of deprotection with TFA or HCl and addition of a new protected amino acid by means of DCC or HOBt. The following amino acids were added successively: Boc-L-proline (IV), Nalpha-Boc-Nomega,N'omega-diethyl-L-homoarginine (VI), Boc-L-leucine (VIII), Nalpha-Boc-Nomega,N'omega-diethyl-D-homoarginine (X) and Boc-L-tyrosine (XII), yielding successively the peptide resins (V), (VII), (IX), (XI) and (XIII).
