Pyrrole derivatives
R 0120
Reaction of α-(N-Carbamoyl)alkylcuprates with Propargyl Substrates: Synthetic
Route to α-Amino Allenes and ∆3-Pyrrolines. — The title reaction affords (N-car32- 122 bamoyl)allenes
in good yields. In most cases the process proceeds in a regiospecific
manner. Deprotection of the products followed by treatment with AgNO3 leads to
∆3-pyrrolines. A wide variety of pyrrolines, including fused and spirocyclic ones, are
available under these conditions. — (DIETER*, R. K.; CHEN, N.; YU, H.; NICE, L.
