C. Lutz et al., Neopentyl and neophyl groups: New nontransferable groups for organocopper and organozine chemistry, SYNTHESIS-S, (2), 1999, pp. 312-316
Neopentyl and Neophyl groups have been found to be excellent nontransferabl
e groups for organozinc and organocopper chemistry. We have shown that mixe
d diorganozincs of the type FG-R-Zn(CH2CMe2R) can be used advantageously fo
r the enantioselective addition to aldehydes. These mixed copper or zinc re
agents are also found to be very efficient in the Michael addition to vario
us activated alkenes.
