There is a significant demand for organic nitriles, based on their versatility in reactions. Compounds prepared from nitriles have properties including superoxide inhibition, ferrielectric liquid crystal dopant, antipicornaviral agents, anti-inflammatory agents, anti-asthma agents, and fibringoen antagonists. The present invention discloses a facile synthesis for 2,4-dihydroxybenzonitrile, and ethers and diethers thereof, from 2,4-dihydroxybenzaldehyde or 2,4-dimethoxybenzaldehyde. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, 2,4-dihydroxybenzonitrile is condensed with (S)-2-methylcysteine.
有机腈的需求很大,因为它们在反应中的多功能性。从腈制备的化合物具有包括超氧化物抑制、铁电液晶掺杂剂、抗肠病毒药物、抗炎药物、抗哮喘药物和纤维蛋白原拮抗剂在内的性质。本发明揭示了一种简便的合成2,4-二羟基苯甲腈及其醚和二醚,从2,4-二羟基苯甲醛或2,4-二甲氧基苯甲醛制备。本发明还揭示了一种制备与脱铁硫胂素相关的一类铁螯合剂的方法,所有这些剂都含有噻唑环。在这种方法中,2,4-二羟基苯甲腈与(S)-2-甲基半胱氨酸缩合。
