1Synthesis of hexacyclic fused isocoumarin framework through selective domino multicyclizations under catalyst and solvent free conditions显示文摘A novel fused isocoumarin skeleton has been synthesized through selective domino multicyclizations by mixing homothallic acid and 2,3-diphenylacryloyl chloride at 200 8C under catalyst and solvent free reaction conditions.Six fused rings with two stereogenic centers were assembled in a convenient onepot operation in good yield.The resulting hexacyclic fused isocoumarin skeleton and its stereochemistry was fully characterized and unambiguously confirmed by X-ray diffraction analysis.Tariq Mahmood Babar Muhammad Moazzam Naseer Muhammad Khawar Rauf Humayun Pervez Masahiro Ebihara Nasim Hasan Rama 2014Chinese Chemical Letters2014,25,9:1
