Vicinal acetylenic derivatives of 2-amino-1,4-naphthoquinone as key precursors of heterocyclic quinones
Shvartsberg,Kolodina,Lebedeva,Fedenok
, p. 582 - 588 (2013/05/09)
The Pd-catalyzed reaction between 3-acetylamino-2-bromo-1,4-naphthoquinones and CuI acetylides prepared in situ gave 3-acetylamino-2-alkynyl-1, 4-naphthoquinones, which were transformed into benz[f]indole-4,9-dione and benzo[g]quinoline-5,10-dione derivatives.

scheme or table, p. 6769 - 6771 (2010/04/27)
A synthetic route to benz[f]indole-4,9-diones from 1,4-naphthoquinone is described. Effective methods for cross-coupling of 3-acetylamino-2-bromo-1,4-naphthoquinone with terminal acetylenes and cyclization of the resulting 3-acetylamino-2-alkynyl-1,4-naphthoquinones are developed.
Substitution of acetylenic groups for halogen in the quinonoid ring
Romanov,Ivanchikova,Moroz,Shvartsberg
, p. 1686 - 1689 (2007/10/03)
The bromine or iodine atom in the quinonoid ring devoid of+M substituent in the position neighboring to the halogen is replaced by acetylenic groups on treatment with CuI acetylides, prepared either beforehand or in situ, in a mixture of DMSO a
