| Synthesis | GENERAL METHOD: To a solution of trifluoroacetic acid (5 mL) of the substrate (1a-1q, 0.15 mmol) was sequentially added hexamethylenetetramine (urotropine, 0.3 mmol) and cuprous oxide (0.15 mmol). The reaction mixture was heated to reflux for 5 h and subsequently cooled to room temperature. A 3 N hydrochloric acid solution (5 mL) was slowly added to the reaction system and stirring was continued for 1 hour. Upon completion of the reaction, the mixture was concentrated under reduced pressure to remove the solvent. The crude product was purified by silica gel column chromatography (200-300 mesh) to afford the target product 3-formyl-4-hydroxybenzoic acid. | | References | [1] Bioconjugate Chemistry, 2018, vol. 29, # 9, p. 2909 - 2919 [2] Dalton Transactions, 2010, vol. 39, # 8, p. 2070 - 2077 [3] European Journal of Inorganic Chemistry, 2012, # 32, p. 5225 - 5238 [4] Research on Chemical Intermediates, 2015, vol. 41, # 11, p. 8147 - 8158 [5] Chemical Communications, 2018, vol. 54, # 42, p. 5385 - 5388 |
