Micowave assisted synthesis of benzo-substituted macrocyclic diamides and their corresponding macrocyclic dithiodiamides

摘要

A synthesis of a series of macrocyclic diamides 3 in good yields by reacting the corresponding bis phenols 4 with the appropriate dihalo alkanes 6 either in solvent or in dry media under microwave irradiation. Thiation of 3 with P2S5 or Lawesson's reagent in solvent free conditions under microwave irradiation is also described.
