摘要

Abstract A reexamination of the reaction of the model actinomycin D chromophore (1a) with DDQ revealed the presence of hitherto unknown 8-hydroxy-substituted phenoxazinone derivative 1c as a minor product along with the 7-hydroxy derivative 1b as the major product. Further, the isomeric hydroxy derivatives can be conveniently converted by reaction with suitable alkyl halides to afford the corresponding alkylated products with suitable ...
