A facile method for the preparation of deuterium labeled salvinorin A: synthesis of [2,2,2-2H3]-salvinorin A.

Salvinorin A is a novel hallucinogen isolated from the widely available leaves of Salvia divinorum. Based on its mechanism of action, salvinorin A has shown potential as a stimulant abuse therapeutic. However, there are no methods for the detection of salvinorin A or its metabolites in biological fluids. In order to begin developing salvinorin A as a potential therapeutic, an understanding of its metabolism is needed. Here, a straightforward synthesis of a deuterium labeled analog of salvinorin A and its utility as an internal standard for the detection of salvinorin A and its metabolites in biological fluids by LC-MS is described.
