<mods:abstract>A simple one-pot protocol for the synthesis of fused&#xd;
pyrrolopiperazines with a complete diastereoselectivity has been&#xd;
developed. This novel methodology combined the Ugi reaction&#xd;
with a spontaneous enamine alkylation on a multicomponent&#xd;
domino reaction, starting from nonprotected diamines and&#xd;
arylglyoxals.</mods:abstract>
