1. Propose a synthesis for either of the following molecules using the indicated starting materials. You don't have to use all of them, but all your carbon atoms must come from them alone. (Hint: A five membered lactone will spontaneously form from the correct hydroxy acid.) If you provide syntheses for both a 10 pt bonus will be awarded. OH со, КCN Br н Н NO, Br NH2 2.

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...
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...
Propose an efficient and elegant synthesis of each of the following molecules using either diethyl malonate or ethyl acetoacetate as your starting material. You may use any alkyl halide or alcohol as your other sources of carbon, and you may use any reagent you deem necessary. CH3 EN CH₂ HCO CH, Hgc CH, CHA CH₃ -CHS
Please help by showing how to do the synthesis for both target molecules! Thank you and please be very thorough with explaining the solvents used and please also provide a retrosynthetic anaylsis with the forward anaylsis. Thanks! 7.
