✦ Synopsis

Preparation and structure of salts and ylides derived from triazolo[l,5-a]quinoline 2 and triazolo[5,1 -a]isoquinoline 3 are described. Reactions with methyl propiolate of ylides 6-9 give pyrrolo[l,2-a]quinolines 13, 18 and pyrrolol2,1-a]isoquinolines 12, 19.

Nucleophilic substitution of 5-bromotriazoloisoquinoline (3) and of 7-bromo-3-methyltriazolopyridine (6) proceeds readily to give a range of 5-substituted triazoloisoquinolines (4a)-(4e), and of 7-substituted triazolopyridines (7a)-(7h) respectively. Triazoloisoquinolines have been converted into 1,
