Synthesis of indolequinones via a Sonogashira coupling/cyclization cascade reaction
摘要:
A mild strategy for constructing indolequinone motifs is described on the basis of the Sonogashira reaction and a copper-catalyzed intramolecular cyclization cascade reaction. The first step involves the palladium- and copper-catalyzed reaction between halogenated naphthoquinone and terminal acetylene to generate a coupling product, which then reacts in a copper-catalyzed intramolecular cyclization with the nitrogen functional group adjacent to the carbon-carbon triple bond.

In this paper, a concise one-pot method for the construction of benzo[f]indole-4,9-dione motifs is described. These transformations proceed via a sequential palladium- and copper-catalyzed coupling reaction of 1,4-naphthoquinones with terminal acetylenes, followed by a copper-catalyzed intramolecular cyclization reaction of the resulting coupling product.

A series of 2-aziridinyl- and 2,3-bis(aziridinyl)-1,4-naphthoquinonyl sulfonate and acylatederivatives has been synthesized and evaluated for antimalarialactivity in vitro against the human malaria parasite, Plasmodium falciparum (Vietnam Smith strain, chloroquine-resistant at the R3 level). The most active compounds, 2-aziridinyl-1,4-naphthoquinon-5-yl p-ethylbenzenesulfonate (13), 2-aziridinyl-1
