Synthesis 10. Give a reasonable synthesis for the following compound from the indicated starting material. You may use any other organic or inorganic reagents you wish unless otherwise indicated. The desired product for each reaction you propose must be the one of the predominant products. Give the reactants, conditions (where appropriate) and products of each synthetic step. NO MECHANISMS!

Synthesis using Carbonyla-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. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...
