Page 7 (23) 10. Synthesis. Determine an appropriate synthetic route to get from the starting material and take it to the products. All the carbons in the products MUST come from the carbons in the starting material (this means you may need to use more than 1 of the starting material molecules). Draw all products, and include all reagents needed. If a product is made that is racemic, draw both enantiomers and write "racemic". A) (13pts)
1. (7 points) Draw the major, organic product generated for each of the reactions regiochemistry and stereochemistry. Be sure to indicate if more than one enantiomer is formed. below. Pay particular attention to the CI dilute H2SO4 KCN C2, H20 (dark) 1. BH3 THF 2. H2O2, KOH 1. NaH 2. allyl chloride (e) Draw the stereoisomer of 2,3-diphenylbut-2-ene that yields meso-2,3-dibromo-2,3-diphenylbutane on reaction with Br2 in the cold, darkness. 2.(2 points) Complete the following synthesis by filing in the missing...
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, e.g. 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. You can...
Predicting Products: Draw the structure of the one major organic product of each reaction in the boxes provided. Be aware that the products all have the molecular formula C6H100, but oth products are constitutional isomers of one another. Stereochemistry should be shown if applicable. HO. Nah, DMSO Br HO, Nah, DMSO Br An efficient way to prepare asymmetrical ethers was developed by a British scientist, Alexander Williamson. Show what reagents you would use to prepare the following compound via a...

this is organic chemistry, please help with both if you can. 1. Give the missing reagents, reactants or products for each of the following reactions. Answer the question associated with part b; if stereochemistry is required, you need to show dashes and wedges on the chiral centers only. (3 pts) a. Hyllindlar H2O/H HI b. give one stereoisomer OH HB/ROOR How many possible stereoisomers are produced? E1 give one stereoisomer PCC Excess H, H CHC12 d. OH KMnO4 HO H...
(10 points) Draw the correct product for the reaction below. For step 2, draw the reaction mechanism. Be sure to include important intermediate compounds, electron flow arrows, and formal charges for full credit. ОН 1. SOCl2, pyridine 2. CH3NH2 (10 points) Fill in the boxes with the missing starting material, intermediate products, reagents, and/or products. Then for each reaction draw the reaction mechanism with Correct electron flow arrows if appropriate or intermediates and correct formal charges. -OH -NH2 NH (10...
Each of these synthetic sequences has an issue in it. Find the issue and then propose a modified synthesis to obtain the target molecules. It may only require a different reagent!
