The abnormal reluctance of piperazic acids to undergo N-2 acylation seems to be due to an electronic effect, not a steric/conformational problem. A system suitable for probing these issues was assembled by methods that have produced a versatile building block for beta-hydroxy-alpha-aminoacids of either relative stereochemistry and of either (L) or (D) configuration.
