Treatment of (R)-1-chloro-2,3-propanediol (I) with either K2CO3 or Cs2CO3 in CH2Cl2, followed by O-protection with Trt-Cl and Et3N in CH2Cl2, yields (S)-trityl glycidol (II). Alternatively, derivative (II) can also be obtained either by direct O-protection of (R)-glycidol (III) by means of Trt-Cl and Et3N in refluxing CH2Cl2 or by cyclization of protected propanediol derivative (IV)--obtained from treatment of compound (I) with Trt-Cl and Et3N in CH2Cl2--by means of KOH in EtOH. Reaction of (S)-trityl glycidol (II) with vinyl magnesium bromide (V) by means of CuI in THF provides (S)-1-(triphenylmethoxy)-4-penten-2-ol (VI), which is then condensed with allyl bromide (VII) with KOtBu or NaH in THF to afford compound (VIII). Ozonolysis of (VIII) in CH2Cl2/MeOH, followed by reductive quench with NaBH4 in NaOH, gives (S)-3-(2-hydroxyethoxy)-4-(triphenylmethoxy)-1-butanol (IX), which is then treated with MsCl/Et3N in CH2Cl2 to yield bismesylate (X). Coupling of compound (X) with 2,3-bis(1H-indol-3-yl)-N-methylmaleimide (XI) [obtained by treatment of dichloromaleic anhydride (XII) with methylamine hydrochloride by means of NaOMe in HOAc to furnish dichloro-N-methylmaleimide (XIII), followed by Grignard reaction of (XIII) with indole (XIV) in toluene/THF by means of EtMgBr in Et2O] by means of Cs2CO3 in DMF gives the 14-membered macrocycle (XV).

Alternatively, compound (XV) can also be obtained as follows: Reduction of (S)-maleate (XVI) with BMS-NaBH4 in THF, followed by O-protection with TBDPS-Cl and imidazole, yields alcohol (XVII), which is first allylated with allyl trichloroacetimidate (XVIII) catalyzed by triflic acid in cyclohexanes and then reduced with DIBAL in THF to provide compound (XIX). Ozonolysis of (XIX) in MeOH, followed by reductive quench with NaBH4, gives diol (XX), which is then converted into bismesylate (XXI) by treatment with MsCl and Et3N in ether. Compound (XXI) is subjected to a double Finkelstein reaction with NaI in acetone in the presence of NaHCO3 to yield bisiodide (XXII) (1), which is then coupled with 3-bis(1H-indol-3-yl)-N-methylmaleimide (XI) by means of Cs2CO3 in DMF to give intermediate (XV).

Hydrolysis of macrocycle (XV) with KOH in refluxing EtOH yields anhydride (XXIII), which is then treated with hexamethyldisilazane (HMDS) and MeOH (in DMF at 80 C) to afford compound (XXIV). Detritylation of (XXIV) with either HCl in CH2Cl2 or HCl in refluxing EtOH gives alcohol (XXV), which is treated with methanesulfonic anhydride and pyridine in either refluxing THF to produce mesylate (XXVI). Finally, the desired product is obtained by reaction of (XXVI) with dimethylamine in THF or DMF. Alternatively, the conversion of (XXV) into the target compound can also be performed by following these steps: treatment of (XXV) with bromine, pyridine and triphenyl phosphite followed by reaction with pyrrolodione provides bromo derivative (XXVII), which is finally converted into the target compound by reaction with dimethylamine in DMF.
