amines, such as substituted anilines, are also efficientunder these conditions. A series of novel conjugated amides have been evaluated for their cytotoxic activities against several human cancer cell lines. A microwave-assisted dehydrative amide condensation reaction is reported as an efficient access to cinnamamide derivatives under solvent-free conditions. This protocol between conjugated carboxylic

Entering the iron age: The first general method for iron‐catalyzed monocarbonylation of alkynes has been developed. A range of structurally diverse cinnamides and acrylamides have been obtained smoothly starting from commercially available amines and alkynes in the presence of [Fe3(CO)12] and ligand L (see scheme). The method is highly chemo‐ and regioselective and requires no expensive catalyst.

The present invention relates to the use of a compound of formula I as a coupling reagent in forming amide or ester bonds from a reaction between a carboxylic acid and an amine or an alcohol, respectively. The compounds of formula I are especially useful as coupling reagents in the preparation of peptide bonds during peptide synthesis. In particular, the compounds of formula I are useful in promoting the formation of reactive reaction intermediates, inhibiting side reactions and in suppression of racemization. In addition, the present invention provides novel compounds of Formula I, and salts of N-oxides thereof.
A highly efficient, two-step, one-pot synthetic strategy for amides and peptides was developed by employing ynamides as novel couplingreagents under extremely mild reaction conditions. The ynamides not only are effective for simple amide and dipeptide synthesis but can also be used for peptide segment condensation. Importantly, no racemization was detected during the activation of chiral carboxylic
