A NEW ACCESS TO THE CLEAVAGE OF THE N-19 BOND OF NORDITERPENOID ALKALOIDS AND THEIR DERIVATIVES BY FORMATION OF OXAZIRIDINES
HETEROCYCLES, Vol. 57, No.12, 2002, pp. 2357～2363, Received, 29th July, 2002，-0001，（）：
A new N,19-seco-norditerpenoid alkaloidal compound (5) possessing an oxaziridine group from yunaconitine (1) was furnished by using a new method in five steps involving acetylation, imination, quaternization, formation of N,O-mixed ketal, and oxidation in 50% overall yields.
