Monday's Molecule #30

Today's molecule looks complicated but it has a very simple, and well-known, name. We need the correct common name and the long systematic (IUPAC) name.

As usual, there's a connection between Monday's molecule and this Wednesday's Nobel Laureate(s). This one is an obvious direct connection. Once you have identified the molecule the Nobel Laureate(s) are obvious.

The reward (free lunch) goes to the person who correctly identifies the exact molecule with the correct formal name and the Nobel Laureate(s). Previous free lunch winners are ineligible for one month from the time they first collected the prize. There are no ineligible candidates for this Wednesday's reward since recent winners have declined the prize on the grounds that they live in another country and can't make it for lunch on Thursday (a feeble excuse, in my opinion).

  2. Is it penicillin G, or known by the IUPAC name as 3,3-dimethyl-6-oxo-7-(2-phenylacetyl)
    heptane-4-carboxylate? The 1945 Nobel prize in physiology or medicine was awarded to Sir Alexander Fleming, Ernst Chain and Sir Howard Florey "for the discovery of penicillin and its curative effect in various infectious diseases".

  3. Congratulations! That's close enough. I think the correct name is, (2S,5R,6R)-3,3-dimethyl
    1-aza-bicyclo [3.2.0] heptane-2-carboxylate.

    Meet me in my office on Thursday at noon for your free lunch at the Faculty Club. RSVP by tomorrow.

  4. Your structural diagram doesn't show any stereoisomerism, so shouldn't the correct name be 3,3-dimethyl
    1-aza-bicyclo [3.2.0] heptane-2-carboxylate?

  5. Sorry I'm unable to make it to lunch.
