Described originally by Ingold (C. K. Ingold, J. Client. Soc., 1921, 119, 305), the effect is discussed more widely in the context of intramolecular reactions by Kirby (

S. Sengupta and V. Snieckus, J. Org. Chem., 1990, 55, 5680. Transacylation could not be stopped in the desfluorosystem. Rapid (<5 s after the addition of carbonyl electrophile) quenching allowed methyl ketones to be isolated; more protracted reactions yielded aldol products.

There are few examples of 1,4-asymmetric induction in reactions of this type. Sengupta and Snieckus (réf. 29) reported a 4:1 excess of one diastereoisomeric series, though the 1,4-reIationship (syn or anti) was not known. See also B. M. Trost and H. Urabe, J. Org. Client., 1990, 55, 3982 for an example of 1,4-asymmetric induction in a Mukaiyama aldol reaction.
