Application of the Noyori annulation reaction to the cephalotaxine spirocycle.
(2001)Cephalotaxine is a naturally occurring alkaloid which is the structural motif of a number of compounds which have shown promising anti-cancer properties. This fact together with its relatively complex pentacyclic structure, ... -
The extractives from Sophora velutina and Calpurnia aurea and their biological activity.
(2012)This work is an account of the phytochemistry and biological activity of two related plant species within the plant family the Fabaceae, Sophora velutina from the subtribe Sophoreae and Calpurnia aurea of the subtribe ... -
Progress towards the pyrrolizidine alkaloid xenovenine (223H) via hydroamination.
(2016)Many natural products, pharmaceuticals and fine chemicals possess carbon-nitrogen bonds and thus the formation of such bonds is of great importance. Pyrrolizidine, indolizidine, quinolizidine and lehmizidine alkaloid ... -
Progress towards the synthesis of Indolizidine alkaloid 223AB
(2008)It has been shown that alkaloids from various sources are vital as lead compounds in medicinal research and thus also the efficient synthesis of these. With the goal of developing a general synthetic route that can potentially ... -
Strategies for the synthesis of benzyltetrahydroisoquinoline alkaloids.
(2011)The objectives of this project were to investigate the application of new methodologies for the preparation of benzyltetrahydroisoquinoline monomers and secondly, to synthesise the bisbenzyltetrahydroisoquinoline neferine ... -
Studies towards the synthesis of perhydropyrrolo[2,1-j]quinoline and perhydropyrido[2,1-j]quinoline ascidian alkaloids.
(2002)Cylindricines A-K [1-11], lepadifonnine [12] and fasicularin [13] are tricyclic ascidian alkaloids exhibiting the perhydropyrrolo[2,1 :j]quinoline and perhydropyrido[2,1-j]quinoline ring systems. The structural features ... -
The use of hydroamination in the attempted synthesis of ant alkaloid 223H (xenovenine).
(2008)The ability to construct C-N bonds is of great importance to organic chemists as exemplified by the vast number of natural products, pharmaceutical agents and fine chemicals that contain such linkages. An atom efficient ...
