合成路线1
该中间体在本合成路线中的序号：(XXV)The condensation of the isoquinoline intermediate (IX) with the naphthaleneboronic acid intermediate (XIX) by means of palladium tetrakis(triphenylphosphine) and NaHCO3 in refluxing ethanol/toluene gives a 5:4 mixture of the (S) and (R) atropaisomers (XXIII), which, without separation, are treated with methanolic HCl to eliminate the methoxymethyl protecting groups and yield a mixture of (S) and (R) (XXIV). The dimerization of this mixture by means of silver oxide in dichloromethane affords a mixture of the (R,R), (R,S) and (S,S) dimers (XXV), which is deprotected with H2 over Pd/C in methanol/dichloromethane and submitted to HPLC to obtain the target (R,S) atropaisomer.
