A new method for the asymmetric synthesis of cycloalkano-2,3-piperid-4-ols by the reaction of a number of chiral enamino ketones with sodium borohydride is proposed.It is shown that the reduction proceeds via 1,4-hydride addition and leads to the formation of primarily one diastereomeric pair of cycloalkano-2,3-popiridols and their dehydration products.The asymmetric synthesis was confirmed by the production of optically active nitrogen-unsubstituted cycloalkano-2,3-piperid-4-ols when the chiral substituent was removed.
