K. Iseki et al., DIASTEREOSELECTIVE TRIFLUOROMETHYLATION OF CHIRAL IMIDE ENOLATES WITHIODOTRIFLUOROMETHANE MEDIATED BY TRIETHYLBORANE, Tetrahedron : asymmetry, 5(6), 1994, pp. 961-974
The trifluoromethylation of lithium enolates of chiral N-acyloxazolidi
nones with iodotrifluoromethane mediated by triethylborane proceeds wi
th good diastereomeric excess.
