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.
Key words
isocyanides - synthesis - alkylation - silver cyanide - Ugi-Smiles - multicomponent reaction

synthesis-Ugi reaction sequence has been reported, the
starting material was already a benzyl isocyanide which was alkylated
under basic treatment:

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