Abstract

We present here a one-pot, four-component sequence that affords Ugi-type adducts starting from simple benzyl or allyl bromides. The isocyanides are prepared in situ under alkylation of silver cyanide salts and the resulting mixture is directly used in a Ugi-Smiles coupling.

Even if these conditions seemed promising, iron salts were abandoned because we failed to perform the one-pot multicomponent couplings with them.
