Problem 1. Using the required reactant, show a multi-step synthesis for each of the target molecules. For the second target molecules, you must choose a reactant. Note, that the equivalencies can be different for the required reactants and that you can you use any reagent/reaction conditions of your choosing to convert the required reactants to product.

Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...
