Show each and every electron flow and bond change using two-headed curved arrows. Overall: NaOET/ETOH First step: Nat OEt + нс Second step: (redraw structure A here) Third Step: + HOF (redraw structure B here) Fourth Step: + Nat -OEL (redraw structure Chere) Fifth Step: (redraw structure D here) - THE END -

Answer 1

The answer and the step-by-step mechanistic detail is provided in the given image as it involves the drawing of complex chemical structures.

First step Dona Nabost re II enolate form. DONGO II This His abstracte because the enclate the formed is more substituted alkene and so more stable Second step than its regio isomer. OPNAÐ Michael Addition, Third step ona + ELOH No out This tautomerises to the more stable keto form. Fourth step o Na HA + -- Na oct - Fifth step N. Etol Intramolecular 6-membered ring formation.
