HIGHLY REGIO-SELECTIVE AND STEREOSELECTIVE ALKYLSUBSTITUTION WITH COPPER REAGENTS FOR THE CONSTRUCTION OF CHIRAL TRIFLUOROMETHYLATED QUATERNARY CARBON CENTERS
S. Hiraoka et al., HIGHLY REGIO-SELECTIVE AND STEREOSELECTIVE ALKYLSUBSTITUTION WITH COPPER REAGENTS FOR THE CONSTRUCTION OF CHIRAL TRIFLUOROMETHYLATED QUATERNARY CARBON CENTERS, Chemical communications, (16), 1997, pp. 1497-1498
A new route for the asymmetric construction of quaternary carbon centr
es containing a trifluoromethyl group has been established using a hig
hly regio-and stereo-selective S(N)2' reaction of organocopper and org
anocuprate reagents with allylic mesylates 4 and 8.
