Topics: Chemistry and Pharmacology

Notes: Acceptor-substituted enynes 1 react with lithium tert-butyl-cyanocuprate [tBuCu(CN)Li] in THF to afford anti-Michael adducts 3. The formation of the isomeric side products 4 can be suppressed by regioselective protonation of the organometallic intermediates with ethanol at -80°C. Evidence for radical intermediates or electron-transfer steps in these reactions could not be obtained.
