β-Acyl substituted unsaturated aldehydes 1 were revealed to be good precursors for the synthesis of various heterocycliccompounds by the combination with tin nucleophiles. Various 2-monosubstituted pyrroles were prepared in an one-pot procedure via the reductive amination of formyl groups of 1 by using Bu2SnIH–HMPA complex. One-pot synthesis of heterocycles was carried out initiated by chemoselective
