This reaction is followed by bromination and rearrangement steps to generate flavonols in the Auwers synthesis. Proline catalyzes an asymmetric version of this reaction used to generate Hajos-Parrish (“high-OHSH-pare-ish”) ketones for steroid synthesis. (-5[1])This reaction forms citrate from oxalo·acetate and acetyl-CoA (15[1])in the first step of the TCA cycle. This reaction’s chair-like (-5[1])intermediate determines its stereochemistry according to the (*) Zimmerman-Traxler model. This reaction follows a Michael addition in the mechanism for the Robinson Annulation. Under basic conditions, (10[1])this reaction’s final step occurs via an E1cB mechanism to form an alpha-beta unsaturated product. For 10 points, name this reaction where an enolate attacks a carbonyl to make a product with both aldehyde and alcohol groups. ■END■ (0[6])
