چکیده
The aconitine-type alkaloids talatisamine (1), 8,14-diacetyltalatisamine (11), and compound 3, the lycoctonine-type alkaloid deltaline (5), and the 7,17-seco C(19)-diterpenoid alkaloids 7 and 9 were treated with HBr-glacial acetic acid to give useful O-demethylated derivatives 2, 2, 4, 6, 8, and 10 respectively in good to high yields (49-90%).

Anticancer Activities of C18-, C19-, C20-, and Bis-Diterpenoid Alkaloids Derived from Genus Aconitum.
Cancer is one of the most common lethal diseases, and natural products have been extensively studied as anticancer agents considering their availability, low toxicity, and economic affordability. Plants belonging to the genus Aconitum have been widely used medically in many Asian countries since ancient times. These plants have been proven effective for treating several types of cancer, such as...
متن کاملExpedient construction of the ABEF azatetracyclic ring systems of lycoctonine-type and 7,17-seco-type C₁₉-diterpenoid alkaloids.
A synthetic strategy for the modeling construction of the highly bridged azatetracyclic ABEF ring system of numerous lycoctonine-type C19-diterpenoid alkaloids bearing a characteristic oxygenated quaternary center at C-7 has been successfully developed. The tetracyclic core was constructed rapidly from a readily prepared 6,7-bicyclic AB ring precursor through a 13-step sequence via an advanced ...

The title compound [systematic name: [(1α,14α,16β)-20-ethyl-8,9,10-trihy-droxy-1,14,16-tri-meth-oxy-aconitan-4-yl 2-amino-benzoate], C30H42N2O8, a natural C19-diterpenoid alkaloid, possesses an aconitane carbon skeleton with four six-membered rings and two five-membered rings. The fused ring system contains two chair, one boat, one twist-boat and two envelope conformations. Intra-molecular N-H⋯...
متن کاملPharmacologically Active C-19 Diterpenoid Alkaloids from the Aerial parts of Aconitum laeve Royle
Two new lycoctonine type C19-diterpenoid alkaloids, swatinine-A (1), and swatinine-B (2), along with four known C19-diterpenoid alkaloids, foresticine (3), neoline (4), delvestine (5), and chasmanine (6), were isolated from the aerial parts of the Aconitum laeve Royle. The structures of compounds 1 and 2 were deduced on the basis of spectroscopic techniques (EI-MS, HREI-MS, H NMR, C NMR, HMQC, ...

To prepare the target nucleosides, the branched chain sugars was converted to their active form (1-bromosugar derivatives). This conversion included the hydrolysis of bromination with hydrobromic acid (HBr) in glacial acetic acid, forming 1-bromo sugars (4,6-di-O-Acetyl-2,3-dideoxy-3,3-di-C-nitro methyl-Darabinohexopyranosyl bromide), which were subjected to condensation with theophylline mercu...
