Abstract Photocyclization of N-arylenamides 10, 15 and 16 led efficiently to spirotricyclic δ-lactams 5, 6 and 7. Compound 7 was easily and stereospecifically transformed in two steps into spirocyclohexylisoquinolines 3 and 4 which show structural analogies with some Amaryllidaceae alkaloids, galanthamine 1 and lycoramine 2.
摘要 N-亚芳基酰胺 10、15 和 16 的光环化有效地产生了螺三环 δ-内酰胺 5、6 和 7。化合物 7 很容易通过立体定向分两步转化为螺环己基异喹啉 3 和 4,它们与一些石蒜科生物碱加兰他敏 1 显示结构相似和lycoramine 2。
