A range of bis-heterocyclic derivatives based on novel morpholinone and triazole heterocycles was prepared from iodo-morpholinone. The key step in our strategy is a one-pot procedure based upon copper-catalysed alkyne-azide cycloaddition (CuAAC) from ...

Methyl 5-iodo-2-methoxybenzoate [PDF]
In the title compound, C9H9IO3, the molecules are close to planar [maximum deviation from benzene ring plane = 0.229 (5) Å for the methyl carboxylate C atom] with the methyl groups oriented away from each other. In the crystal, molecules form stacked layers parallel to theabplane, where every layer has either the iodine or methoxy/methyl carboxylate ...

Late‐Stage Modification of Halotryptophan‐Containing Peptides Via Negishi Cross‐Coupling
Negishi cross‐coupling provides access to the late‐stage functionalization of bromotryptophan‐containing peptides under comparatively mild conditions and is applicable to a range of peptide substrates in the investigated model systems. The examined alkyl iodides and variation of N‐terminal residues demonstrate the feasibility of the transformation in a

Nickel‐Catalyzed Reductive Cross‐Coupling of Xanthate Esters With Aryl and Alkenyl Iodides
A nickel‐catalyzed reductive cross‐coupling of xanthate esters and aryl/alkenyl iodides is reported without the need for separate activators for the xanthate esters. The reaction utilizes a relatively low catalyst loading. Diarylmethanes with a good functional group variety can thus be synthesized indirectly from the corresponding benzylic alcohols ...
