Synthesis of substituted (D)-phenylalanine derivatives by regioselective reduction of enantiomerically pure cis-2,3-disubstituted aziridines

Add time:07/28/2019    Source:sciencedirect.com

Various N-(R)-(+)-(α-methylbenzyl)-(2R,3R)-disubstituted aziridines were prepared by intramolecular cyclization. The regioselective reduction of the ring C(3)-N bond in the presence of (Boc)2O by catalytic hydrogenation with atmospheric pressure of hydrogen provides (D)-phenylalaninol analogues in good yields.
