Abstract
Cyclooctyne underwent 1,3-dipolar cycloaddition with pyridinium bis(methoxy -carbonyl)methylides to afford the corresponding indolizines (8-methoxycarb onyl-7-azatricyclo[7.6.0.0(2,7)]pentadeca-1,3,5,8-tetraenes) in good to mod erate yields, Some molecular orbital considerations are also described on t his reaction compared with the results on the reaction of pyridinium dicyan omethylides with cyclooctyne.
