Compound 8-(trans-3-ethoxycarbonylallylacetyl)heptafulvene,8, undergoes both an intramolecular [8+2] cycloaddition and a 10π-electron electrocyclization followed by 1,5-sigmatropic hydrogen shifts to give10 and12, respectively.
化合物8-(反式-3-乙氧基羰基烯丙基乙酰基)庚烯酮8经历分子内[8 + 2]环加成和10π电子电环化,然后分别进行1,5-σ氢转移,得到10和12。
