Each "step" (reaction arrow) may consist of one or more chemical
reactions; if the latter is the case, the structure (s) of all
intermediates must be revalued.

("step I" and "step II"). Indicate the necessary reagents for "step
I" and "step II", and write down the structure of the
intermediate.
b. Indicate necessary reagents for "step III".
c. Indicate necessary reagents for "step IV". In "step IV", in
addition to the product shown, 17 more by-products are formed.
Write down the structure of the by-product that is formed most of
and explain why it is not possible to convert 15 to 18 under
similar reaction conditions as used in "step IV".
d. Indicate necessary reagents for "step V".
e. The conversion of 18 to 19 can be performed by two reactions
("step VI" and "step VII"). Indicate the necessary reagents for
"step VI" and "step VII", and write down the structure of the
intermediate.
