THE STRUCTURE DETERMINATION OF A NEW ALKALOID PHLEGMARIUINE-N BY LONG-RANGE TWO-DIMENSIONAL AND NOE DIFFERENCE NMR SPECTROSCOPY
A new alkaloid, phlegmariuine-N, was isolated from Phlegmariurus fordii (Baker) Ching. In the present work, a technique of long-range 1H-1H and ~(13)C-1H COSY in combination with NOE difference spectroscopy has been successfully used to connect the spin systems separated by quaterrnary carbons and heteroatom. Its structure has been elucidated as (Ⅰ).
