8. Give products or required starting materials for these crossed-Claisen condensations that use two different esters. Note that the first ester is added to the base to form an enolate. (If the base were added to the ester, enolates would form and react with the ester present in the flask). Give the enolate for the first reaction. 1) O 2) OK iPro ОMe Meo t-butoxide THF 1) 2) N LÝ OMe Eto Meo LDA 1) 2) Meo Оме Eto LDA...

Predict the products for the following reactions. Note – think
about the base being used – is it catalytic? If so, can the product
molecule ring-close?
