Question
Answer the following about Robert Woodward’s contributions to total syntheses, for 10 points each.
[10e] Woodward led the Harvard team, which joined forces with Albert Eschenmoser’s ETH team, in the total synthesis of this compound. This largest B vitamin’s central corrin ring contains a cobalt atom.
ANSWER: vitamin B12 [or cobalamin]
[10m] The first step of Woodward’s classic strychnine (“STRICK-neen”) synthesis begins with a Fischer indole synthesis, involving a phenyl derivative of this compound. The Olin Raschig process produces this compound found in rocket fuels.
ANSWER: hydrazine [or N2H4; accept phenylhydrazine]
[10h] Woodward and Doering’s 1944 total synthesis of quinine stood until this chemist published a stereoselective pathway in 2001. Carbonyls are selectively alkylated in this chemist’s namesake enamine synthesis.
ANSWER: Gilbert Stork [accept Stork enamine synthesis]
