Facile syntheses of enantiopure 3-hydroxypiperidine derivatives and 3-hydroxypipecolic acids.
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.
