Volume: 5 Issue: 34 Issue date: 2015 Publication year: 2015 Pages: 26972-26976 Language: English E-ISSN: 20462069 CODEN: RSCACL Document type: Journal article (JA) Publisher: Royal Society of Chemistry Abstract: Two consecutive N-heterocyclic carbene (NHC) catalytic systems were combined in a one-pot cascade reaction for the assembly of aromatic aldehydes and 2-haloenals into a structurally complex ¦Ã-lactone backbone. To our knowledge, this is the first report of NHC-catalyzed [3 + 2] annulation of ¦Á,¦Â-unsaturated acylazoliums with 1,2-bisnucleophiles. © The Royal Society of Chemistry 2015.
