Liu, Gang published the artcileBenzofused tricycles based on 2-quinoxalinol. [Erratum to document cited in CA146:251809], Application In Synthesis of 19788-49-9, the publication is Journal of Combinatorial Chemistry (2008), 10(2), 343, database is CAplus.
The quinoxalin-2-ol mol. structure published in the article has been recently corrected to be quinoxalin-2-one by X-ray single-crystal anal. of an unambiguous configuration of chem. compound 1, which indicated that it was a 3,4-dihydroquinoxalin-2-one but not a quinoxalin-2-ol. The correct chem. structure for Compound 1 as synthesized by a published standard method is given in supplemental Figure 1.
