A. Touche et al., A GENERAL NMR APPROACH FOR THE STRUCTURAL DETERMINATION OF ALKALOIDS - APPLICATION TO 3-BETA-HYDROXYLUPANINE, Journal of agricultural and food chemistry, 45(6), 1997, pp. 2148-2152
The structure of 3-beta-hydroxylupanine, a major alkaloid isolated fro
m the seeds of Lupin us mutabilis S., was unequivocally established th
rough dedicated H-1 and C-13 NMR experiments, thus revealing a novel g
eneral strategy for error-free structural assignment of lupine alkaloi
