For any two of the molecules below, outline both a retrosynthetic analysis and a forward synthesis...
(ii) ost For the molecule above: (a) Draw all stereoisomers. Identify a pair of enantiomers AND identify a pair of diastereomers. [10 marks] (b) Devise both a retrosynthesis and a corresponding forward synthesis. Each of your building blocks should not incorporate more than ten carbon atoms of the target molecule. (Note: your synthesis does not need to be stereoselective). [10 marks]
5. (12 pts) For the molecules below, provide a retrosynthetic analysis to starting materials that satisfy the conditions given. Then give a step-by-step synthetic plan. You may use any reagents you want to accomplish your synthesis. OH O from starting materials containing three or fewer carbon atoms from starting materials containing two or fewer carbon atoms
(d) Perform a retrosynthetic analysis of molecule A. Using propiophenone as starting material outline the forward synthesis also. Explain how a similar route could be taken to afford a mixture of diastercoisomers B and C OH OH propiophenone
using any reagents show retrosynthetic analysis and then show
entire synthesis in forward sense
SIcP f youl proposed syninesis. from Target molecule
SIcP f youl proposed syninesis. from Target molecule
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. (16 pts) Synthesize the target molecules using only the carbon sources provided and any reagents of your choosing. Target Molecules Carbon Sources Br Br HO CH3 CH
6. (12 pts) For each the molecules below, provide a retrosynthetic analysis and then give a step-by- step synthetic plan. All the carbon atoms in the final products must come from molecules in the box at the bottom. You may use any other reagents you want to accomplish your synthesis. H3CH2CO Acceptable Carbon Sources: " i hool.com ormar BCH,NH iicuch " OCH CH3
Please answer both
When performing a retrosynthetic analysis for the desired synthesis below, what is the best question to ask first? Br CH3-C=CH Br To what functional group can two adjacent bromine atoms be added? Which alkyl halide is needed for the synthesis? How can I deprotonate an alkyne? What reagents are needed to alkylate an alkyne? What is most likely the initial retrosynthetic disconnection of the target molecule in the given synthetic transformation (i.e., the last step of the...
