Treatment of 14-methylsulfonyl pseudaconine 3 with DMF-NaOH at 150 °C for 10 h afforded the desired C-nor and 12,13-seco norditerpenoid alkaloids 16α-methoxyl ketone 7 (70%) and 16β-methoxyl ketone 8 (15%) as a pair of epimers. Reaction of 7 with Br2-HOAc at room temperature for 1.5-2 h produced the phenols 9 (40%), 10 (10%) and 13 (29%). Whereas, treatment of 8 with Br2-HOAc under same conditions as the case for 7 gave phenolic compound 9 (38%) besides the by-product α-bromoketone 14 (25%).

3α,13-Dihydroxyforesaconitine (1) was isolated from the roots of Aconitum forestii Stapf.It was identified as the 8-O-acetyl-14-O-(4-methoxybenzoyl) derivate of 3α,8β,13,14α-tetrahydroxy-1α,6α,16β-trimethoxy-4β-(methoxymethyl)aconitane (2).Substructures of 2 obtained by hydrolysis of 1 were derived from two-dimensional carbon-proton and proton-proton shift correlations.
