Abstract
Moranoline, or 2-hydroxymethyl-3,4,5-trihydroxy piperidine, is prepared by directly reducing an actinomycetes culture solution containing nojirimycin, followed by isolation, as for example, through the utilization of an ion exchange resin. The corresponding N-methyl derivative can be obtained through the addition of formaldehyde to the culture solution prior to the reduction.
