The naturally occurring 3-oxohexanoyl-L-homoserinelactone (1a), a bacterial autoinducer, has been prepared in 47 % overall yield by condensing stable 3-oxohexanoic acid (2), prepared by hydrolysis from the corresponding ester (3), with L-homoserinelactone using hydroxybenzotriazole (HOBT) and dicyclohexylcarbodiimide (DCC) in non-aqueous media.
天然存在的3-氧代己酰基-L-高丝氨酸内酯(1a)是一种细菌自诱导剂,通过将稳定的3-氧代己酸(2)(由相应的酯(3)水解而制得)与L缩合,以47%的总收率制备。非水介质中使用羟基苯并三唑(HOBT)和二环己基碳二亚胺(DCC)合成-高丝氨酸内酯。
