In the presence of Li-TMP and an aromatic aldehyde, benzocyclobutenone undergoes an unusual heterolytic C(1)C(4) bond fission, and subsequent reaction with the aldehyde gives, after acidic workup, isochroman-3-one in high yield.
在Li-
TMP和芳族醛的存在下,
苯并环丁烯酮经历不寻常的杂化C(1)C(4)键裂变,随后与该醛反应,经过酸性处理后,高产率地得到
异色满-3-酮。
