Abstract

[GRAPHICS]alpha-Aminoalkylcuprates prepared from CUX . SLiCl (X = Cl, CN) and 1 equiv of an alpha-lithiocarbamate undergo conjugate addition reactions to alpha,beta-alkynyl ketones in moderate to good yields, affording E:Z mixtures ofalpha,beta-enones. Treatment of the conjugate adducts with PhOH/TMSCl in CH2Cl2, effected carbamate deprotection and cyclization to afford a flexibletwo-step synthesis of substituted pyrroles.
