8. (12pts) Provide the necessary reagent(s) to transform vinylcyclohexane into the part A and B products. If more than one set of reagents is needed, then number the order in which you would use them. H vinylcyclohexane
For the following reaction sequence, supply the missing intermediate or reagent/solvent, as appropriate Extra Credit: For the following reaction sequence, supply the missing intermediate or reagent/solvent, as appropriate. 1) 2) H", H,O Br DMF Extra Credit: Over the arrow, write in the reagents needed to perform the following transformation. Be specific about the number of equivalents (moles) required for each reagent and about the order of the steps Br
show all of steps required to achieve the transformation shown below. For each step include all applicable starting material(s), solvent(s), reagents or catalysts required. You should show each step as a balanced reaction, but you do not need to draw full mechanisms. [3.0 Marks 0
Write the specific reagent(s) necessary to effect the transformation shown for both of the following two (2) questions. If more than one reaction is involved in individual steps clearly. Include stoichiometric coefficients of reagents, as well. an answer, be certain to distinguish the A. -c=N Ph Ph B. CH3 CH3 OH HO Br (racemic)
Consider the following reaction: OH HC H.SO CH, + ОН Δ Show the complete mechanism for the following transformations. Make sure to show all arrows depicting the movement of electrons. The above reaction (using acid and heat) causes a number of unwanted side products to form (a big mess). Propose a better synthesis for the product using the same starting materials. Show the reagents and intermediate steps to complete the synthesis: OH H3C- ??? + CH3 OH X steps Propose...
Struggling to find a solution to this. Please draw the mechanism for me so I can better understand. Multi-Step Synthesis Given the following reaction, develop a synthesis to complete the transformation. - Draw out all intermediates and every reagent needed to complete the synthesis. - You do not need to draw the mechanism (unless it helps you) Hint: This requires multiple steps/intermediates/reagents and there is more than one possible route. ОН + En
1) Provide the missing reagents to complete each transformation. (Need to use correct reagents in CORRECT order) 3. (20pts) Provide the missing reagents needed to complete each transformation below. Each arrow represents a single reaction. Do not exceed the number or reactions allowed for each transformation. You will have to use the correct combination of reagents in the correct order to receive full credit. (4pts for correct reagents and correct order for each transformation a-e)
Fill in appropriate reagents and conditions to complete the reactions in the scheme below. If you need multiple steps for one transformation, make sure to number them appropriately (and only one step per box please).
Complete the reaction scheme. Complete structures are required; if a reagent has a common abbreviation, then the abbreviation can be used but must be completely correct. Sequential steps should be numbered. Include stereochemistry as appropriate. 15. The Robinson Annulation combines two reactions to form a cyclica.B-unsaturated ketone. Provide the dicarbonyl intermediate and the final product. You do not need to worry about stereochemistry 15a. Draw the expected intermediate son OH (solvent) 10 15b. Predict the product. 10
Please explain the mechanisms! 1. Propose a synthesis for each of the following problems starting with reagent shown and using any other organic or inorganic reagents allowed in each problem. Multiple steps are required. The number of steps you use does not matter. Reactions should give the desired product as a major product. For full credit show the product of each step (reaction). If you make use of organometallic reagents such as Grignard, Wittig, organolithium, organosodium, organocopper, etc. you must...
