environmentally friendly synthesis of Fmoc-N-methyl α- and β-amino acids from the corresponding Fmoc-amino acid, via intermediate oxazolidinones/oxazinanones, has been developed. Microwave heating for 3 min was required for the synthesis of the oxazinanones, while their Lewis acid catalyzed reductive opening only needed 1 min for completion. Hence, Fmoc-N-methyl-amino acids, suitable for, for example
已经开发了通过中间体恶唑烷酮/恶二酮酮从相应的Fmoc-氨基酸高效且环保的合成Fmoc- N-甲基α-和β-氨基酸的方法。恶唑烷酮的合成需要微波加热3分钟,而路易斯酸催化的还原开孔仅需1分钟即可完成。因此,适用于例如固相肽合成的Fmoc- N-甲基氨基酸可容易地在不到1小时内由相应的Fmoc氨基酸制备,包括纯化。将Fmoc-β 3 -homophenyl丙氨酸表明未预料到的反应性,并提供了一个单步路线高度有用的Fmoc保护的1,2,3,4- tetrahydroisoquinolineaceticacid,即β-hTic类似物。
