Hernandez-Torres, Gloria,Mateo, Julio,Urbano, Antonio,Carreno, M. Carmen
, p. 6259 - 6262 (2013)
Access to the eight-membered cyclic ether (rac)- and (-)-cis-lauthisan was achieved in two complementary ways in only four steps for the longest linear sequence by starting from commercially available materials. The sequence features a cis-stereoselective reductive cyclization as the key step. Copyright

A green method for the sulfination of allenic carbonyl compounds to access a wide variety of vinylic sulfones is developed. This reaction works in aqueous media under very mild conditions. This reaction is atom economic. A wide variety of vinylic sulfones could be obtained in moderate to excellent yields with wide functional group tolerance. The efficiency of this method is demonstrated in some reactions where the desired products can be isolated by filtration.

The propargylation of aldehydes promoted by microwave irradiation using allenylboron compounds in a chemo- and regioselective way is described. The corresponding products were obtained in short reaction time, high yield and purity without the need of any solvent when allenylboronic acid pinacol ester was used, or using a minimal amount of acetone when potassium allenyltrifluoroborate was used.
