Abstract
Use of conformational constraints, induced by different ortho-substituents in 1-allyloxy-2- (substituted) methylbenzenes, where the substituent is a 1, 3-dipole such as the azide or 3- oxidopyridinium group, can be employed to accelerate the 1, 3-dipolar cycloaddition reaction. In this manner cycloadditions that otherwise do not proceed can be forced to react.
