New polyhydroxylated pyrrolidine, piperidine, and pyrrolizidine alkaloids from Scilla sibirica.

Abstract:

Chromatographic separation of an extract of the bulbs of Scilla sibirica resulted in the isolation of five pyrrolidines, two pyrrolidine glycosides, six piperidines, one piperidine glycoside, and eight pyrrolizidines. 2,5-Dideoxy-2,5-imino-glycero-d-manno-heptitol (homoDMDP, 1) is a common alkaloid in all plants of the Hyacinthaceae examined to date and was also found in S. sibirica. The structures of the new alkaloids were elucidated by spectroscopic methods as 7-deoxy-homoDMDP (4), 2,5-dide...
