Cyclopentadiene

Good introduction. Good results, good discussion.

Taxol

There are two chairs for each of 9 and 10; you report only one? In table 4, what are the (H) isomers? Other configuration around the alkene? why is this relevant? But I see where yo are going with eg Table 5, to investigate further. Well done!!

NMR

Good discussion, but what is the geometry of your system? Chair? Which chair? What about the dithiane ring? Table6 could be presented in a more visual manner, which would show immediately any outliers? Does Table 6 relate to a twist boat? Where are the results for eg a chair then? Nicely set out discussion!

Epoxides

X ray

Did you measure any anomeric alignments (between a bond and say an idealised lone pair)> It is very revealing!

Nice analysis of the Jacobsen.

NMR

Good results. Did you consider any spin spin couplings in your analysis? You just quote dd!

Rotations

Table 9, which enantiomer is it for? You do not say which for either your calculation or the literature. This is the very crux of the entire expt, and you have missed this key point of your reporting. There is no discussion at all for 4.3! The most important section!

TS

For styrene oxide, the prediction is a 24% ee in favour of S. Does this match expt? You dont tell us! We do get an answer for the stilbene oxide at least!

NCI

A bit short. I guess you ran out of time at this point!

Overall, pretty good in places, especially at the start when you had lots of time, but I think you did not leave yourself enough time to do the really important bits as well.
