Magnesium bisamides as reagents in synthesis

As part of the continued requirement for more selective reagents in organic synthesis, magnesium bis-amides are becoming established as a class of org anometallic bases with considerable potential. Their relatively mild reacti vity, combined with their high degree of steric congestion, leads to a dist inct class of reagents with significantly different chemo-, regio-, stereo- and enantioselectivities when compared with existing species and protocols .
