Kinetic resolution in rhodium-catalyzed [5+2] cycloisomerization

Kinetic resolution in rhodium-catalyzed [5+2] cycloisomerization

<p>This thesis demonstrates the ability of a rhodium(I)-phosphoramidite catalyst to effect the first examples of kinetic resolution in [5+2] cycloisomerization (Scheme i). This methodology was applied to a range of diversely substituted enyne substrates, including a novel chiral silane tether....
