Irradiation of benzofurazan (1) in benzene solution yields the azepine derivative 3 as the main photoproduct. Addition of methanol in the dark to the irradiated benzene solution of 1 results in the isolation of 3 together with a new product, methyl-1-cis, 3-cis-N-(4-cyano-buta-1, 3-dien-1-yl)-carbamate (1-cis, 3-cis-2). Irradiation of 1 in methanol solution gives a mixture of the stereoisomeric methyl
在苯溶液中辐照苯并呋喃酯(1)产生了氮杂ze衍生物3作为主要光产物。在黑暗中将甲醇添加到1的苯辐射溶液中,结果分离出3和一种新产物,即甲基-1-顺,3-顺-N-(4-氰基-buta-1、3-二烯基-哌嗪-1-基) -氨基甲酸酯(1-顺,3-顺式- 2)。照射1在甲醇溶液中给出了立体异构甲基N-(4-氰基-丁-1,3-二烯-1-基)-carbamates的混合物,从该1-反,3-顺式的异构体2 可以以纯净形式分离。
