Highly enantioselective photodeconjugation of α,β-unsaturated esters. Origin of the chiral discrimination
The photodeconjugation of α-methyl conjugated esters can be highly enantioselective when carried out in CH2Cl2 or hexane in the presence of catalytic amounts of chiral β-amino alcohols. Enantiomeric excesses (ee %) up to 70% are desc
