We were attracted to substrate that can be susceptible to an allylic hydrogen abstraction to form an allylic radical based on our compounds that containing an allylic N- or S-substituent.
As abstraction may be the dominant mechanism, there is a higher allylic hydrogen concentration in isoprene (7 vs.
Pharmacological studies have demonstrated that andrographolide supports conceptual hydrogen transfer, which would be thermodynamically favoured for its allylic hydrogen on carbon C-11.
It has been suggested that the loss in scorch safety is primarily attributed to the elimination of degradative chain transfer reactions as the groups of Type I coagents quickly react with the alkoxy radical and do not possess an allylic hydrogen.
