Yield:1078-61-1 95%
Reaction Conditions:
with 10% palladium on activated charcoal;hydrogen in acetone at 20; for 3 h;
Steps:
4.6. Preparation of saturated caffeic acid (22)
Five percentage palladium on activated carbon (20 mg) was added to caffeic acid (2, 100 mg) in acetone (l mL). The heterogeneous mixture was stirred under a hydrogen atmosphere at room temperature for 3 h. The mixture was filtered through celite which afforded a saturated caffeic acid (22, 95 mg, 95%) as a brown crystal.Saturated caffeic acid (= 3-(3,4-Dihydroxyphenyl)propanoic acid) (22): IR νmax (film) 1715 cm-1; 1H NMR (CD3OD, 500 MHz): δ 6.62 (1H, d, J = 7.6 Hz; H-5'), 6.59 (1H, d, J = 1.5 Hz; H-2'), 6.48 (1H, dd, J = 7.6, 1.5 Hz; H-6'), 2.71 (2H, t, J = 7.6 Hz; H-3), 2.47 (2H, t, J = 7.6 Hz; H-2); EIMS m/z 182 [M]+, 123 (base).
