Caudatosides A-F: New iridoid glucosides from Citharexylum caudatum

Six new iridoid glucosides, caudatosides A-F (2-7), and one known iridoid glucoside, 5-deoxypulchelloside I (1), were isolated from the fruits of Citharexylum caudatum. The structures of these compounds were elucidated by various one- and two-dimensional NMR techniques as well as high-resolution negative-ion ESIMS. Other plant parts were extracted on a small scale, and TLC of these extracts revealed the presence of the same iridoids.

Conversion of 5-Deoxypulchelloside I to Caudatoside A

The iridoid caudatoside A (2) was synthesized in seven steps from the naturally occurring iridoid 5-deoxypulchelloside I (1) using a straightforward series of protection and deprotection procedures to introduce the requisite C-6 cinnamoyl ester.
