  amides is reported. The mechanistic studies suggest the reaction occurs via a single electron transfer pathway. Based on the DFT electronic structure calculations of various reaction pathways, the most plausible mechanism involves the formation of a phenyl radical cation and an arenium ion as the key intermediates. It represents the first example that p‐anisaldehyde is employed as a formyl source via

  Enamides, dienamides, and enynamides are important building blocks in synthetic, biological, and medicinal chemistry as well as materials science. Despite the extensive breath of their potential utility in synthetic chemistry, there is a lack of simple, high-yielding methods to deliver them efficiently and as single isomers. In this paper, we present a novel, protecting group free, efficient, and stereoselective approach to the generation of beta-halo-enamides. The methodology presented provides a robust synthetic platform from which E- or Z-enamides can be generated in good yields and with complete stereocontrol.

  Iodo-enamides were synthesised in a single step, in good yield and with complete selectivity from N-formyl imides. The beta-iodo-enamides are stable and were converted efficiently into novel geometrically defined beta-yn-enamides. (C) 2011 Elsevier Ltd. All rights reserved.
