The fast access to simple (Z)-3-iodo acrylic acid derivatives which can be easily oxidized to the corresponding hypervalent iodine(III) reagents Is described. They can be used for various reactions with superior or similar reactivity as conventional hypervalent iodine(III) reagents.

A selective one-pot procedure was developed for the production of E-dihalo-substituted α,β-unsaturated alkenoic acids and derivatives from the corresponding α,β-unsaturated alkynoic acids.
This reviews surveys the preparation of a great diversity of complex biorelevant gamma-lactam backbones thanks to scalable copper(I)-catalyzed cascade multicomponent processes.
