Macmillan Lear For the dehydrohalogenation (E2) reaction, draw the Zaitsev product, showing the stereochemistry clearly. You might find it helpful to make a model of the starting material to determine the correct conformation. Hi 1114 KOH EtOH heat

Draw the major product(s) of the following reactions, if there is a reaction. Be sure to include stereochemistry in your products. H30* 3 l2 NaOH но OH H30* 1. LDA, THF 2.

If deuterated borane were used instead of borane in the hydroboration oxidation of the alkene shown below, what would be the expected product? (D = ²H) D OH 1) BD 3 2) H₂O₂, NaOH orto OH od + enantiomer + enantiomer OD + enantiomer OD + enantiomer ?

Provide the major product(s) of each reaction below. Show the stereochemistry of each stereocenter (for example, by using wedge-dash structures for chirality centers and clear bond angles for alkenes). For enantiomers, you only need to draw one of the enantiomers. Br2, H₂O 1) 03 2) MeSMe H₂, Pd/C HgSO4 H₂SO4 H₂O 1) BH3 2) NaOH, H₂O2 H₂O 1) 9-BBN 2) NaOH, H₂O2 H₂O

C ← 1750 Draw the two major products of this reaction. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers, Ignore inorganic byproducts. 1. BH3-THF 2.H2O2, NaOH, H₂O Select to Draw + V o Proble

Draw the product(s) you would expect from the following reaction. CH3 H₂C CH3 CH₂ + H₂C=CHCCH3 heat • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just give one.

Draw the major and minor product that could be formed when 2-methoxy-1,3- butadiene reacts with propenoic acid. Ignore any stereochemistry. O H3CO. magpla OH

What is the missing starting material or product? Show stereochemistry and mechanism as needed.

K Draw the major product from this reaction. Use wedge and dash bonds to indicate relative stereochemistry where appropriate. Ignore acid byproducts. E 1 E RCO3H I LE 1 L # Q

Predict the products of the following reactions. Include stereochemistry when necessary. For reactions with more than one step show the product formed after each step.
