SYNTHESIS AND TRANSFORMATIONS OF NOVEL BENZOCFURANS

摘要

Some novel 1-cyanoisobenzofurans have been synthesized by a convenient ring closure methodology. The new products easily reacted with electron-deficient olefins . and acetylenes to yield Diels-Alder products. Theoretical calculations satisfactorily support the quinonoide character of the new isobenzofuran derivatives.
