1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols.

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...
