1-(6-Carboxyhexyl)-5-[(E)-3-hydroxy-1-octenyl]midazole, an imidazole analogue of prostaglandin, was synthesized from 4(5)-hydroxymethylimidazole hydrochloride. The key step involves regioselective alkylation of 4(5)-tertbutyldimethylsilyloxymethylimidazole to give predominantly 1, 5-disubstituted imidazole.
1-(6-羧基己基)-5-[(E)-3-羟基-1-辛烯基]咪唑,一种前列腺素的咪唑类似物,由4(5)-羟甲基咪唑盐酸盐合成。关键步骤包括对4(5)-叔丁基二甲基硅氧甲基咪唑进行位点选择性烷基化,以得到主要1,5-二取代的咪唑。
