  Dibenzonaphthyridinones: Heterocycle-to-Heterocycle Synthetic Strategies and Photophysical Studies

  摘要：

  A heterocycle-to-heterocycle strategy is presented for the preparation of highly fluorescent and solvatochromic dibenzonaphthyridinones (DBNs) via methodology that leads to the formation of a tertiary, spiro-fused carbon center. A linear correlation between the results of photophysical experiments and time dependent density functional theory calculations was observed for the lambda(max) of excitation for DBNs with varying electronic character.

  Reductive heterocycle–heterocycle (heterocycle → heterocycle; H–H) transformations that give 4-aminoquinolines, 3-acylindoles, and quinolin-4(1H)-ones from 2-nitrophenyl substituted isoxazoles are reported. When this methodology is applied to 3,5-, 4,5-, and 3,4-bis(2-nitrophenyl)isoxazoles, chemoselective heterocyclization gives quinolin-4(1H)-ones, and 4-aminoquinolines, exclusively.

  据报道，还原性杂环 - 杂环（杂环 → 杂环；H–H）转化为 4-氨基喹啉、3-酰基吲哚和喹啉-4（1 H）-从 2-硝基苯基取代的异恶唑转化。当此方法应用于 3,5-、4,5- 和 3,4-双（2-硝基苯基）异恶唑时，化学选择性杂环化会专门生成喹啉-4（1 H）-酮和 4-氨基喹啉。
