    1. The problem statement, all variables and given/known data


    Ok here it is molecule B.


    Ok and here it is problem nr. 8, second molecule.

    2. Relevant equations

    No equations needed.

    3. The attempt at a solution

    So why is it that we do not add any acid here, as far as I know one need acid, in order to do a succesfull carbonlyl or conjugate addition, right? So how come? And because it is LiMe (which is a hard nucleophile) I think it will be a carbonyl addition, so am I right?

    Well I did not really get that far as I am really not sure how to produce an ether from conjugate addition... So how to?

    Yes, you are correct. Why can't you draw the initially-formed product (before acid is added)?

    There is a hint in the previous problem. I'm not sure how to do this in one step but it's possible in two.
