摘要：
It is shown that the reaction of conjugated ynones containing a phosphoryl group with o-phenylenediamines can, depending on the conditions, lead to the selective formation of phosphorylated 1,5-benzodiazepines and quinoxalines. Phosphorylated quinoxalines can be used for synthesis of substituted vinyl quinoxalines.
