It is shown that the complexation of Eu(fod) 3 with the MTPA ester of trans ‐4‐ tert ‐butylcyclohexanol is very similar to that of ketones with Eu(fod) 3 . It is found to be more likely that the MTPA moiety can exist as two rotamers, suggesting that earlier models for correlating LIS and absolute configuration are inadequate.
