Question

Answer the following about the Wieland-Miescher ketone and its use in total synthesis, for 10 points each.
[10h] This chemist’s total synthesis of Taxol uses a single enantiomer of the Wieland-Miescher ketone as a starting material. A butadiene derivative named after this chemist exhibits unusual reactivity in Diels-Alder reactions.
ANSWER: Samuel J. Danishefsky [accept Danishefsky’s diene or Danishefsky Taxol total synthesis]
[10m] In their work on total syntheses, Hajos (“HOY-yosh”) and Parrish recorded the synthesis of the Wieland-Miescher ketone via this reaction. This two-step reaction consists of a Michael addition followed by an aldol condensation.
ANSWER: Robinson annulation
[10e] The AB-ring structure of the Wieland-Miescher ketone makes it an attractive starting material for the synthesis of this class of compounds, which are characterized by four fused rings and include estradiol and testosterone.
ANSWER: steroids [accept steroid hormones]
