Both enantiomers of cis-6-(hydroxymethyl)- and cis,cis-4-hydroxy-6-(hydroxymethyl)pipecolic acids, piperidine-based nonproteinogenic amino acids, have been synthesized from starting materials obtained from enzymatic desymmetrizations.

Piperidine-based compounds are an important class of natural alkaloids found in plants, insects, and amphibians. A general asymmetric synthesis of 2-alkyl-6-methylpiperidines is presented via the enzymatic desymmetrization of meso cis-2,6- and cis,cis-2,4,6-substituted piperidines with Aspergillus niger lipase (ANL). The enzymatic reaction proceeds in excellent chemical yield and high enantiotopic selectivity (ee ≥ 98%). The general method is used to effect the synthesis of (±)-dihydropinidine-HCl as well as the first asymmetric synthesis of dendrobate alkaloid (+)-241D.
