Structural and stereochemical studies of saraines: Macrocyclic alkaloids of the sponge Reniera sarai

Tetrahedron

Abstract

The absolute stereochemistry of saraines A-C (2-4), a class of unusual polycyclic alkaloids from the Mediterranean sponge Reniera sarai, has been elucidated by applying high field H-1-NMR to Mosher's method. The structures of saraine-B (3) and saraine-C (4), only partially clarified previously, now have been fully characterized by extensive analysis of their NMR spectra.
