Enantiodivergent synthesis of the enantio-pure cis,cis 3-protected 2,6
-disubstituted piperidin-3-ol 1 has been achieved via a biochemical me
thod, and the absolute stereochemistry of (+)-1 has been established b
y its conversion into the known piperidine (-)-17. The utility of 1 as
a chiral building block for alkaloid synthesis is demonstrated by the
total synthesis of (-)-cassine and (+)-spectaline.
