An efficient synthesis of 2-cyano-2-phenyl-2,11b-dihydro-[1,3]oxazino[2,3-a]isoquinolines by reaction of isoquinoline with electron-deficient acetylenes in the presence of benzoylcyanide
摘要:
Isoquinoline reacts with electron-deficient acetylenic compounds in the presence of benzoylcyanide to form 2-cyano-2-phenyl-2,11b-dihydro-[1,3]oxazino[2,3-a]isoquinolines in good yields.

GRAPHICAL ABSTRACT ABSTRACT Novel 1,4-diionic organophosphorus compounds have been obtained efficiently from the one-pot three-component reaction of triphenylphosphine, diaroylacetylenes and 5-aryl-4-quinoxalin-2-yl-furan-2,3-diones in 1,2-dichloroethane. The synthesized compounds were characterized by different spectroscopic methods and their structure was confirmed in one case by single crystal X-ray
