Good Morning,
I want to know what the approach detailed reaction mechanism for the following year.

I propose
1. Reaction 2,2-Dihydroxy-5-methyl-1H-indene-1,3 (2H) -dione with the carbanion formed between the tertiary amide and Cyanogen
2.Aunque I doubt if a Michael reaction between carbanion formed and alpha-beta unsaturated occurs.

I am attentive to your comments

Beforehand thank you very much

What do you think is the first step?
Where do you see bond-formation, bond-breaking?
