Give the answer with proper examples and percent yield.

Q. What are the EFFECT OF THE SUBSTITUENTS PRESENT ON 1,2- AZABORINES? The above observations could be explained on the basis of the catalyst used, the substituents present on the 1,2-azaborine, the type of dienophile used, the aromaticity of diene, the secondary interactions involved and the deformation energy required to adopt the transition state geometry.
