Abstract: | Enantiomeric excesses of up to 99 % could be obtained in the synthesis of the biologically interesting acylated α-aminophosphinic acids 1 (R1=Me, Ph; R2=H, Me, Et; R3=H, F, iPr) by asymmetric hydrogenation with rhodium complex catalysts and subsequent hydrolysis Eq. (1)]. cod=1,5-cyclooctadiene. |
