When irradiated at λ = 366 nm or at λ = 420 nm in the presence of an appropriate sensitiser the title compounds underwent a di-π-methane rearrangement which led to the formation of tricyclic azasemibullvalenones (2a,2a1,2b,4a-tetrahydroazacyclopropa[cd]pentalenones) in yields of 63–87%.
当在照射λ = 366纳米或在λ在适当的敏化剂的标题化合物的存在= 420nm处进行了二π
甲烷重排而导致
三环azasemibullvalenones的形成(2一,2一1,2 b, 4一个-tetrahydroazacyclopropa [ CD ] pentalenones)中的63-87%的产率。
