Provide a reasonable arrow-pushing mechanism for the following transformation. (Hint! The reaction involves both intramolecular v. addition and aldol reactions. C1 is labeled in the starting material and product.) NaOE/EtOH но
5(a). Predict the product for the following reaction.
(b). Provide an arrow-pushing mechanism for the reaction above that
accounts for the formation of the product. Explicitly include all
non-bonding electrons and charges. Indicate whether each step is an
initiation, chain propagation, or termination.
(c). An additional product, shown below, is formed in the reaction
from part (a). Provide an arrow-pushing mechanism that accounts for
the formation of the
additional product. (You may start from any intermediate from part
(b))....
