A "Two-fer" entry

Today's entry is a two-for-one special, covering Monday's class and today.

On Monday we covered a portion of Chapter 27 and learned how to create terpenoids, or molecules that are derived from the combination of functional equivalents of isoprene. The processes that we saw are generally reactions that we know (Claisen, aldol, decarboxylation, loss of water to make stable carbon cations, etc.) with one new reaction thrown in: the use of NADH or NADPH as a hydride source. We also saw that it is possible to create a wide variety of different terpenoids by rearranging the structures.

Today was exam #4, hopefully it went well for everyone. I won't be able to start grading them until tomorrow so at this point my guess is that they will be ready to be returned on Monday.
