A new approach to the synthesis of the CC-1065/duocarmycin pharmacophore
摘要:
The spirocyclic 1,2,7,7a-tetrahydrocycloprop-[1,2-c]indol-4-one subunit of CC-1065 and duocarmycin A, which comprises the common pharmacophore of the two antibiotics, has been efficiently synthesized in six steps from readily available starting materials. The key step of the synthesis utilizes a zirconocene-stabilized benzyne complex.

The development of a new method for the regiospecific synthesis of polysubstituted indoles and indolines is reported. The key steps involve the generation of zirconocene-stabilized benzyne complexes and subsequent intramolecular olefin insertion reactions to provide tricyclic indoline zirconacycles. The zirconacyclic intermediates were cleaved with iodine to yield diiodo indolines, which were converted to a wide variety of indole and indoline products, such as analogs of tryptamine, serotonin, tryptophan, and the pharmacophore of CC-1065.
Total synthesis of makaluvamine A/D, damirone B, batzelline C, makaluvone, and isobatzelline C featuring one-pot benzyne-mediated cyclization–functionalization
Total synthesis of pyrroloquinoline alkaloids, such as makaluvamine A/D, damironeB, batzelline C, makaluvone, and isobatzelline C, was achieved featuring a one-pot benzyne-mediated cyclization–functionalization reaction. The synthetic utility was demonstrated by the construction of the common pyrrolo[4,3,2-de]quinoline skeleton.
