Zusammenfassung
Enantiomerically pure 3- and 4-substituted phosphonic acid derivatives 5 of pyroglutamic acid were prepared by a Michael addition of the lithiated (+)-camphor derivative 2 to α,β-unsaturated esters and subsequent hydrolysis. The reduction of the lactams 5 with LiBH4/BF3·OEtz afforded substituted phosphonic acid analogues 7 of proline.
