VERSATILE METHODS OF SYNTHESIS OF 5 TO 8-MEMBERED RING N-HETEROCYCLES VIA INTRAMOLECULAR CYCLOADDITIONS OF ALLYLAMINES

Rai, K. M. Lokanatha,Hassner, Alfred

, p. 817 - 830 (2007/10/02)

N-Tosylallylamines or homoallylamines were monoalkylated with dibromoalkanes to produce bromoalkylamines 3 or 7.The latter were converted to unsaturated nitro derivatives which, via nitrile oxides, underwent intramolecular cycloaddition to form hetero rin
