These reactions have been found to be most selective when using both chiral BINAP and the triflate leaving group. Of note is that this (R)-BINAP determination of selectivity will only occur in systems that are electron rich.

WebApr 30, 1999 · The experiments described above indicate that chiral information is transferred from the (S)-chiral centers in the tails of1 to the cores, where it is amplified to give right-handed helical fibers, which then further pack into left-handed supercoils. If this analysis is correct, it should be possible to block the chirality transfer by forcing ...
