Novel Reactivity of SeO2 with 1,3-Dienes: Selenophene Formation
摘要:
A novel and efficient method for the synthesis of selenophenes is disclosed. Selenophenes were synthesized in high yields in a single operation from 1,3-dienes containing a carbonyl group at the C-1 position and selenium dioxide. The bidirectional synthesis of selenophenes can also be demonstrated using this method. The selenophene is believed to form via a [4 + 2] cycloaddition between diene and selenium dioxide.

The present invention relates to a pharmaceutical composition or a functional health food comprising a verbenone derivative and pharmaceutically acceptable salts thereof as active ingredients for treating or preventing a neurodegenerative disease. More specifically, the verbenone derivative according to the present invention reduces neuronal cell death and oxidative stress, and is highly effective in preventing ischemic brain damage and inflammatory cell migration in rats, thereby providing the pharmaceutical composition or the functional health food which is useful in treating neurodegenerative diseases.

Discovery of novel (1S)-(−)-verbenone derivatives with anti-oxidant and anti-ischemic effects
A series of novel (1S)-(−)-verbenone derivatives was synthesized bearing a 4-styryl scaffold. The synthesized compounds were tested for their anti-oxidant, anti-excitotoxic, and anti-ischemic activities. These derivatives significantly reduced oxygen–glucose deprivation-induced neuronal injury and N-methyl-d-aspartic acid-evoked excitotoxicity in cortical neurons. Furthermore, compound 3f was identified
