The 13C labeled olefination reagents1 were developed to simplify the labeling process by providing a set of substrates ready to be incorporated into precedented chemical syntheses.2 These olefination reagents provide access to a fi xed 13C label within the alkene as well as site-variable deuterium incorporation (Scheme 1). This methodology efficiently provides a densely labeled compound ready for further functionalization.

Scheme 1: Olefination reagents labeling strategies.

The availability of all three sulfur oxidation states allows control of the reaction conditions including base type and strength as well as access to a preferred sulfur removal strategy.3 By providing access to mild reaction conditions, fewer compatibility issues arise between reaction conditions, olefination reagent and substrate.
