An efficient route to the α-methyl ester of L-glutamic acid, and its conversion into cis-5-hydroxy-L-pipecolic acid

, p. 349 - 350 (1996)
The treatment of the N-benzyloxycarbonyl α-methyl esters of L-glutamine or L-asparagine with tert-butyl nitrite in refluxing acetonitrile results in selective hydrolysis of the amide group, giving optically pure Z-Glu-OMe (74%) or Z-Asp-OMe (88%); these are versatile chiral building blocks, and an efficient synthesis of cis-5-hydroxy-L-pipecolic acid from Z-Glu-OMe is described.

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.
