1. ChemInform Abstract: Efficient Cyclization of Tertiary Amines and Alkenes Promoted by KOt-Bu-DMF.

Author

Chen, Yan‐yan, Zhang, Xue‐jing, Yuan, Hui‐min, Wei, Wen‐tao, and Yan, Ming

Subjects
*RING formation (Chemistry), *AMINES, *ALKENES, *POTASSIUM compounds, *DIMETHYLFORMAMIDE, *QUINOLINE derivatives, *INDOLINE
Abstract

The 6-endo-cyclization of substrates (VI) and (VIII) gives rise to corresponding tetrahydroquinoline derivatives, whilst the reaction of substrate (XI) leads to indoline (XII) as a result of a 5-exo-cyclization. [ABSTRACT FROM AUTHOR]
