Carbene cyclisation cycloaddition cascade
« on: May 14, 2020, 09:40:34 AM »
Hi,
Im trying to do a past paper and I am stuck on this question. I need to find a mechanism for the reaction of N to O. I am given some of the intermediates Q and P.
Can anyone point me in the right direction. I cant find answers online and my teacher is off becuase of the virus.

The final step is a 3+2 cycloaddition with the alkene + the 1,3-dipole that's produced.
