An efficient solvent-free synthesis of a variety of highly pure 1,3-sn-diglycerides (1,3-sn-diacylglycerols) in a two-step one pot process is described. Heating glycerol carbonate (4-hydroxymethyl-1,3-dioxolan-2-one) with fatty acid anhydrides 2a-d affords 1:1 mixtures of glycerol carbonate fatty esters 3a-3d and the corresponding fatty acids. Further heating the reaction mixtures in the presence of catalytic amounts of 1,4-diazabicyclo[2.2.2]octane (DABCO) at 195-200 °C yields highly pure 1,3-sn-diglycerides 4a-4d. © 2012 AOCS.

2-Ethylhexanoic acid has been used as a dual solvent-catalyst for the one-pot, four-component synthesis of 1,2,4,5- tetrasubstituted imidazoles. This naturally occurring and widely produced fatty acid exhibited remarkable catalytic activity and was easily separated by extraction. The reusability of this catalytic medium was tested by recovering the catalyst and using it again in the reaction up to four times with no significant drop in activity. The catalyst is commercially available, of low cost and ecofriendly, offering short reaction times (30-90 min), very good to excellent yields (88-93) and a straightforward workup procedure. © 2015, Gazi University Eti Mahallesi.
