COUNTERION EFFECTS ON GEOMETRIC CONTROL IN THE PETERSON REACTION OF BISTRIMETHYLSILYL ESTERS: SYNTHETIC SCOPE AND MECHANISTIC IMPLICATIONS
An interesting and useful level of geometric control can be realized in the reaction of enolates derived from bistrimethylsilyl acetates and aldehydes leading to α-trimethylsilyl esters and derived compounds depending upon the cation employed.Mechanistic
Chiral ligand-controlled asymmetric conjugate addition of lithium amides to enoates
The external chiral ligand-controlled asymmetric conjugate addition reaction of lithium amides with α,β-unsaturated esters provided β-amino esters in high yields and high enantioselectivities. Copyright
