A tandem reaction of a new type of Baylis-Hillman adduct, such as R-C6H4CCl=CH(OH)C(CH2)CO2R1 (R = 4-MeO, 4-NO2, 4-Me, H, 4-F, 3-Cl; R1 = Me, Et) was promoted by the ionic liquid 1-hexyl-3-methylimidazolium·HSO4/NaNO3 system and the unexpected products 6-aryl-2H-pyran-3-carboxylates and the corresponding imidazolium salts I (R = 4-NO2, H, 3-Cl, 4-F, R1 = Me; R = 4-NO2, 4-F, R1 = Et) were efficiently formed via rearrangement and substitution reactions. While mediated by 1-ethyl-3-methylimidazolium·HSO4/NaNO3 system, the key intermediates, nitrates II (R = 4-OMe, 4-F, R1 = Me; R = 3-Cl, R1 = Et) were isolated. A plausible mechanism for the transformation was given. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Related Products of 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Related Products of 478935-29-4
