  摘要：

  N-烯酰基吲哚的紫外光照射可形成具有与相应的分子间反应相反的区域化学性质的分子内[2 + 2]光环加成产物；相比之下，N-烯基氧羧基吲哚似乎相对光稳定，因为它们在激发态寿命内保持在一个不活泼的构象中。

  A visible-light-induced method for the construction of heterocyclic scaffolds such as pyrido[1,2-a]indoles and indolizines via sulfonyl radical-triggered relay cyclization without employing any external photocatalyst has been developed. Preliminary mechanistic investigation indicated that indole and pyrrole derivatives could serve as pre-photocatalysts to promote the sulfonylation/cyclization, thereby

• Intramolecular photochemical cycloadditions of N-alkenyloxycarbonylindoles and N-alkenoylindoles

  日期：——

  Ultraviolet light irradiation of N-alkenoylindoles affords intramolecular [2 + 2] photocycloadducts with regiochemistry opposite to that obtained in the corresponding intermolecular reaction; in contrast, N-alkenyloxycarbonylindoles appear to be relatively photostable because they are frozen in an unreactive conformation for the duration of the excited state lifetime.

• Intramolecular Photochemical Cycloaddition Reactions of N-[(.omega.-Alkenyloxy)carbonyl]indoles and N-(.omega.-Alkenoyl)indoles

  日期：1994.3

  Ultraviolet light irradiation of N-(but-3'-enoyl)indole (3i), N-(pent-4'-enoyl)indole (3j), and N-(hex-5'-enoyl) indole (3k) affords intramolecular photocycloadducts 17a-19a in which the termini of the side-chain alkene have become bonded to the 2- and 3-positions of the indole ring. The regiochemistry of the addition of the alkene is the opposite to that obtained in the corresponding intermolecular reaction of an N-acylindole with a monosubstituted alkene. The length of the methylene linkage between the tethered alkene and the N-acyl activating group in these N-alkenoylindoles affects the quantum efficiency of intramolecular cycloaddition as well as the ability of the reaction to compete with intermolecular cycloaddition in the presence of added cyclopentene. In contrast, the N-(omega-alkenyloxycarbonyl)indoles 3a-e are relatively photostable, apparently because they are frozen in an unreactive conformation for the duration of the excited state lifetime. Compounds 3a-e are, however, capable of undergoing intermolecular photocycloaddition in the presence of added alkenes and they also photodimerize. These reaction pathways dominate when lower energy wavelengths (lambda>300 nm) of ultraviolet light are used; irradiations performed at higher, energy wavelength (254 nm) give predominantly photo-Fries rearrangement products.
