Yield:116-31-4 95%
Reaction Conditions:
in water at 20; for 0.0833333 h;Knoevenagel Condensation;
Steps:
13 Step 13
1) To a solution of 0.31 g of 3-methyl-2-butenal in 8 mL of water, quickly add 0.12 g of β-C15 aldehyde and stir at room temperature. 2) After 5 minutes, filter the resulting solid and dry it. 0.39 g (yield 95%) of all trans retinal was obtained. This stage is characterized by Knoevenagel condensation and all trans retinal formation.
