A new pentacyclic monoterpenoid indole alkaloid glycoside named secorubenine (1) was isolated from the heartwood of Adina rubescens, collected in Indonesia. The structure was elucidated by spectroscopic analysis and chemical modification of isolated

The palladium-mediated intramolecular biarylation of the cyclic triamide of 2-bromo-4-(isobutylamino)benzoic acid proceeded effectively by the introduction of three methyl groups and the use of tri-tert-butylphosphine as the ligand.

A collective synthesis of glycosylated monoterpenoid indole alkaloids is reported. A highly diastereoselective Pictet-Spengler reaction with α-cyanotryptamine and secologanin tetraacetate as substrates, followed by a reductive decyanation reaction,

The first enantioselective total syntheses of (-)-secologanin (1), (-)-5-carboxystrictosidine (2), and (-)-rubenine (3) were accomplished in 10, 9, and 14 steps, respectively. The key transformation in the synthesis of 1 was a sequential anti-selecti
