The structure of saraine A [3], an unprecedented nitrogenous metabolite from the Mediterranean sponge Reniera sarai, has been investigated mainly by means of 2D nmr methods. Although an acetate derivative 2 of saraine A was previously described by X-ray analysis, the underivatized product showed some spectroscopic anomalies that can be explained by the existence in 3 of a strong ''proximity effect'' involving an aldehyde moiety and the nitrogen atom of a tertiary amine group.

Abstract

The structure of saraine A [3], an unprecedented nitrogenous metabolite from the Mediterranean sponge Reniera sarai, has been investigated mainly by means of 2D nmr methods. Although an acetate derivative 2 of saraine A was previously described by X-ray analysis, the underivatized product showed some spectroscopic anomalies that can be explained by the existence in 3 of a strong ''proximity effect'' involving an aldehyde moiety and the nitrogen atom of a tertiary amine group.
