The stereochemistry that describes the C=C bond remains the same in the product.
(b)
Interpretation:
A synthetic step for the given transformation, including reagents and special reaction conditions in the forward direction, is to be written.
Concept introduction:
Synthesis may be designed by thinking in the reverse direction, from the product to the starting compound, in a method called retrosynthesis. A synthesis is a specific sequence of chemical reactions that converts the starting materials into the desired compound, called the target (or synthetic target). The product given in the retrosynthetic step is the precursor for the synthetic step, followed by an arrow
In a hydroboration-oxidation reaction, H-OH adds to an alkene in a syn fashion, with anti-Markovnikov regiochemistry, to produce an alcohol.

- 1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on the LC-MS printout. How much different are they? 2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit, explain what each of these is and why they are present. 3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by calculating the accurate monoisotopic mass. 4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source. 5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number).
