Photochemistry of ortho-Azidocinnamoyl Derivatives: Facile and Modular Synthesis of 2-Acylated Indoles and 2-Substituted Quinolines under Solvent Control
The light-promoted potential of ortho -azidocinnamoyl compounds is evaluated for heterocycle synthesis. Depending on the nature of the solvent, 2-acylated indoles were obtained under aprotic conditions, whereas the use of a protic medium led to 2-substituted quinolines. The synthetic significance of this metal-free method is that, by simply changing the solvent, the reaction outcome can be directed
Preparations of the novel fused dimethoxyquinoline derivatives of furo[2,3-b]quinoline (5), s-triazolo[4,3-a]quinoline (8) and tetrazolo[1,5-a]quinoline (10) from 6,7-dimethoxy-3-carboxyquinoline-1-oxide (1) are reported.

Preparation of Alkoxyquinoline Derivatives and Their Evaluation as Potential Central Nervous System Stimulants
A variety of substituted amides of 6,7-dimethoxy-2-hydroxyquinoline-3-carboxylic acid were synthesized. Three of these compounds, tested as potentialcentralnervoussystemstimulants, showed no marked biological activity.
