Michael addition of the metallated camphor derivatives 2 to vinylogous esters and subsequential hydrolysis afforded phosphonic analogues of glutamic acid. The enantiomerically pure lactam 6 was reduced by LiBH4/BF3·OEt2 to phosphoproline 7.
将金属化的樟脑衍生物2迈克尔加成到乙烯基酯中,随后水解,得到谷氨酸的膦酸类似物。对映体纯的内酰胺6被LiBH 4 / BF 3 ·OEt 2还原为磷酸脯氨酸7。
