The Structure of a New Piperidine Derivative from Buckwheat Seeds (Fagopyrum esculentumMoench)

Allelopathy of buckwheat: Assessment of allelopathic potential of extract of aerial parts of buckwheat and identification of fagomine and other related alkaloids as allelochemicals

“…Compound 1 was isolated as colorless needles (37 mg), [α] D = + 20.5° ( c = 1, water, observed), [α] D + 23 (water; c = 1 reported), and was identified as fagomine (Koyama & Sakamura 1974). The 1 H and 13 C NMR spectroscopic data of compound 1 were in accordance with those reported in other papers (Koyama & Sakamura 1974; Asano et al . 2000).…”

Efficient and Stereodivergent Syntheses of D‐ and L‐Fagomines and Their Analogues

“…[1,2] 1,2-Dideoxy-azasugars represent a small but an important class of glycosidase inhibitors. [12] Fagomine (1, Scheme 1), a member of this family, was isolated from the seeds of Japanese buckwheat Fagopyrum esculentum australe Moench [13] and also from the seeds of Castanospermum australe (Leguminosae). [14] Recently, isomers of fagomine such as 2 and 3 have been isolated from the leaves and roots of the legume Xanthocersis zambesiaca.…”

Recent advances in the chemistry of azapyranose sugars

“…23 A further DNJ analogue is the 1,2-dideoxynojirimycin, fagomine 17. Initially found in the seeds of Fagopyrum esculentum (Polygonaceae) seeds, 24 it was later discovered in the leaves and roots of Xanthocercis zambesiaca (Leguminosae) together with 3-epifagomine 18, 3,4-diepifagomine 19, fagomine-4-O-b-D D-glucopyranoside, and fagomine-3-O-b-D D-glucopyranoside. 25 Fagomine analogues, 6-deoxy-fagomine 20 and a-1-C-ethyl-fagomine 21 were isolated from Lycium chinense (Solanaceae) roots 26 and Campanulaceae, respectively.…”
