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).
