The synthesis and chemistry of a monocyclic analogue of neocarzinostatin chromophore are described.This analogue is activated through a Michael addition process and provides cycloaromatized products similar to those obtained in the activation of neocarzinostatin chromophore.Mechanistic studies on this analogue have led to the first identification of a diyl self-quenching pathway based on a 1,5-hydrogen atom transfer that provides a novel hypothesis about the relationship between thiol structure and DNA single and double strand cleavage selectivity for neocarzinostatin chromophore and diyl-based cleaving agents.
Studies on DNA cleaving agents: Synthesis and chemically induced cycloaromatization of a monocyclic neocarzinostatin chromophore analogue

The synthesis of an acyclic analogue of neocarzinostatin chromophore is described. This analogue is found to undergo cycloaromatization in the presence of thiols; the process involves a previously undetected internal hydrogen abstraction reaction.

The preparation of 1-carboalkoxy-1,3-dihydrobenzenothiophene 2,2-dioxides via rhodium acetate or rhodium trifluoro-acetate catalyzed decomposition of α-diazo-β-arylmethanesulfonyl esters is described.The reaction has been extended to yield 1,3-dihydrothiophene 2,2-dioxides fused to the 2,3 position of thiophene and indole, but not of furans.In the latter case products derived from the opening of the furan ring were obtained.Key words: synthesis, 1-carboalkoxy-1,3-dihydrobenzothiophene 2,2-dioxides, intramolecular carbenoid insertions, rhodium acetate catalysis.
