  Chiron approach to formal synthesis of both antipodes of cis 3-hydroxypipecolic acid

  摘要：

  The efficient and practical formal syntheses of both enantiomers of cis 3-hydroxypipecolic acid were accomplished from cis aziridine-2-carboxylate as the common synthetic precursor. The key steps involved are stereo and regioselective aziridine ring opening, reductive cyclization and selective N-debenzylation over O-debenzylation reactions. (C) 2014 Elsevier Ltd.

  Facile Syntheses of Enantiopure 3-Hydroxypiperidine Derivatives and 3-Hydroxypipecolic Acids

  摘要：

  Facile syntheses of enantiopure trans- and cis-3-hydroxypiperidine derivatives and 3-hydroxypipecolic acids are reported, featuring Rh-catalyzed cyclohydrocarbonylation through common intermediates. A diaxial conformation in a 2,3-disubstituted N-Boc-piperidinyl structure is revealed by an X-ray crystallographic analysis.

  A stereoselective synthesis of N-Boc-protected cis-(2R,3S)-3-hydroxy pipecolic acid, starting from d-glucose is described. The key step in the overall synthesis is a highly regioselective reductive cleavage of benzylidene acetal 13 leading to hydroxymethyl piperidine derivative 14.
