1. Predict the major organic products of the following reactions. For each problem you are asked to list factors that you considered in your decisions of what product is made. 1. PBr3 2. OH SNa Collect Information: i. Characteristics of starting material that may be important: ii. Characteristics of reagents in step 1 iii. Characteristics of reagents in step 2 Identify Products Identify possible first steps, follow reaction pathway and draw mechanisms, circle reactive intermediates Distinguishing/Deciding on products Consider regioselectivity,...
*Ignore the structures drawn in pencil. The purple lines
indicate that they are incorrect.
23. As 5 points. Complete 10 of the 15 following reactions by providing the missing information: reactants products or reagents and conditions. When predicting products, you must include all products that will most likely form in an appreciable amount. When more than one product is likely, label the major and minor products. (Watch out for rearrangements). Where appropriate, indicate stereochemistry, as well as whether or not...
Draw the missing major organic product(s), starting
material(s), or reagents for each of the following reactions (DO
NOT WRITE +EN AS A PRODUCT (ie draw everything out!)! And remember
stereo and regiochemistry.) Assume reagents are in excess unless
otherwise indicated. **To make things simple, I indicated what is
needed for each section! Please don't just put the answers, but
explanations as well on why. Thanks!
a) draw the starting material for this reaction.
b) draw the product for this reaction....
9-17. Syntheses: draw / provide the likely organic product(s) generated in each of the reactions (or reaction sequences) below. As appropriate, pay attention to regiospecificity (new bond formation and location in the product formed) and stereochemistry (direction in space of new bond[s] formed). Indicate ALL likely products; where one product does not predominate, label / indicate the MAJOR product(s). Where a product mix results, indicate the MINOR or TRACE product(s). (12 pts) 9. First, exhaustively alkylate, then add Ag20 and...
2. Synthesis: Fill in the missing products in the synthesis process below. Stereochemistry should be shown if applicable. Br m-CPBA NaOEt DMSO H+ MeOH 1. Predicting Products/reagents: Draw the structure of the reagents or the major organic product(s) of each reaction in the boxes provided. Stereochemistry should be shown if applicable. 1) xs LAH, Et20 2) H20 CI HO CI OH CI pyridine
For each of the following reactions fill in the box to give the
missing product(s). If no reaction occurs, write N.R. If the
reaction produces a mixture of products, such as stereoisomers or
constitutional isomers, give the structure of each product. If a
major product arises, label it as so. Be sure to show
stereochemistry when needed.
