CHIRAL SYNTHESIS OF 5-HYDROXY-(L)-PIPECOLIC ACIDS FROM (L)-GLUTAMIC ACID

Bailey, Patrick D.,Bryans, Justin S.

, p. 2231 - 2234 (2007/10/02)

A stereo- and enantio-specific synthesis of the naturally occuring cis-5-hydroxy-(L)-pipecolic acid (3) is described, starting from Z-(L)-glutamic acid; the key step involves cyclisation of a protected chlorohydrin, and also gives access to trans-5-hydroxy-(L)-pipecolic acid.
