Asymmetric Simmons-Smith Cyclopropanation Of α,β-Unsaturated Bornane-2,3-Diol Acetals
摘要:
Reaction of selected alpha,beta-unsaturated aldehydes with bornane-2-exo,3-exo-diol has afforded a series of novel chiral acetals which on treatment with a Simmons-Smith reagent,undergo diastereoselective(46-70 %d.e.) cyclopropanation.
