Pericolactines A–C, a New Class of Diterpenoid Alkaloids with Unusual Tetracyclic Skeleton
نویسندگان
چکیده
Fusicoccane diterpenoids usually possess a fused 5-8-5 tricyclic ring system, which are biogenetically generated from geranylgeranyl diphosphate (GGDP). In our report, three novel diterpenoid alkaloids with fusicoccane skeleton, pericolactines A-C (1-3), were isolated from Periconia sp.. Their structures with absolute configurations were determined by spectroscopic analyses and quantum chemical ECD calculation. Pericolactines A-C (1-3) are a new class of diterpenoid alkaloids with an unusual fused 5-5-8-5 tetracyclic ring system, which derive from a geranylgeranyl diphosphate (GGDP) and serine conjugated biosynthesis. They belong to the atypical diterpenoid alkaloids.

Expedient 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 ...
متن کاملA NEW STRATEGY FOR THE SYNTHESIS OF TRICYCLIC AND TETRACYCLIC SYSTEMS OF INDOLE ALKALOIDS
Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...

Paniculatine 1, magnellanine 2. and magnellaninone 3 are three structurally similar tetracyclic alkaloids isolated and characterized by Castillo in 1976.3 Despite their unusual and interesting structures, there has been a paucity of effort directed toward the synthesis of this class of alkaloids.3 We report hem our studies on the synthesis and characterization of two tricyclic intermediates whi...
متن کاملStudies on C20-Diterpenoid Alkaloids: Synthesis of the Hetidine Framework and Its Application to the Synthesis of Dihydronavirine and the Atisine Skeleton
The full details of a synthesis of the hetidine framework of the C20-diterpenoid alkaloids and its conversion to the atisine core structure are reported. The application of the hetidine framework to the synthesis of dihydronavirine, which is the formal reduction product of the natural product navirine, is also described. Key to the success of these studies is the use of a Ga(III)-catalyzed cycl...
متن کاملTwo new diterpenoid alkaloids, beiwusines A and B, from Aconitum kusnezoffii.
Two new atisine-type diterpenoid alkaloids, beiwusine A (1) and B (2), have been isolated from the roots of Aconitum kusnezoffii Reichb. Their structures were established on the basis of spectroscopic data. Beiwusines A and B are the first examples of atisine-type diterpenoid alkaloids having a hydroxyl group at C-1. In addition, one known diterpenoid alkaloid spiramine H (3) has been isolated.
