✦ Synopsis

Preparation of Substituted Alkylpyrroles via Samarium-Catalyzed Three-Component Coupling Reaction of Aldehydes, Amines, and Nitroalkanes.

-Pyrroles of type (IV) are prepared from saturated aldehydes in the presence of a catalytic amount SmCl 3 under mild conditions. If Ξ±,Ξ²-unsaturated aldehydes or ketones are coupled with butylamine and nitroethane the corresponding pyrroles are formed in the absence of any catalyst. -(SHIRAISHI, H.
