合成路线3
该中间体在本合成路线中的序号:(IX)Coupling of the chiral auxiliary (R)-proline (I) with methacryloyl chloride (II) under Schotten-Baumann conditions provided amide (III). This was converted to bromolactone (IV) by asymmetric bromolactonization in the presence of N-bromosuccinimide. Subsequent acid hydrolysis yielded the chiral (R)-bromoacid (V), that was converted to acid chloride (VI) and then coupled with 4-amino-2-trifluoromethylbenzonitrile (VII) in DMA at low temperature to afford anilide (VIII). Coupling with 4-aminothiophenol (IX) using NaH in THF produced sulfide (X). Finally, conversion of the aniline precursor (X) to the target isothiocyanate was achieved by reaction with thiophosgene in the presence of NaHCO3.
