Interestingly, a clear trend is found: in the case of the (−)-GTM-3-catalyzed system, a notably higher ratio for the formation of secondary products is observed for those derived from the RR -TSO reactant (red line), which reacts mostly through the S N 1 mechanism, and the opposite is found for the (+)-GTM-3 catalyst, with a higher formation of secondary products from the less reactive SS -TSO reactant (blue line).
