Oelschlaeger, Herbert,Fritsch, Helmut
, p. 834 - 839 (1984)
3,5-Dinitrobenzoic anhydride is available from 3,5-dinitrobenzoyl chloride by limited hydrolysis in THF/pyridine.The procedure is safe and provides excellent yields.
2,6-Dimethyl-4-nitrobenzoic anhydride (DMNBA): An effective coupling reagent for the synthesis of carboxylic esters and lactones
Shiina, Isamu,Miyao, Ryo
experimental part, p. 1313 - 1328 (2009/07/05)
Various carboxylic esters are obtained at room temperature in excellent yields with high chemoselectivities from nearly equimolar amounts of carboxylic acids and alcohols using 2,6-dimethyl-4-nitrobenzoic anhydride with triethylamine by the promotion of 4-(dimethylamino)pyridine. The efficiency of the esterification is compared to those of other dehydrations using substituted benzoic anhydrides as coupling reagents. This method was successfully applied to the synthesis of threo-aleuritic acid lactone and the desired 17-membered ring compound was prepared in high yield at room temperature from the corresponding free trihydroxycarboxylic acid using 2,6-dimethyl-4-nitrobenzoic anhydride in the presence of 4-(dimethylamino)pyridine.
Dabco/SOCl2, mild, and convenient reagent for the preparation of symmetrical carboxylic acid anhydrides
Kazemi, Foad,Kiasat, Ali Reza
, p. 2287 - 2291 (2007/10/03)
Various types of carboxylic acids undergo rapid dehydration with 1,4-diazabicyclo[2.2.2]octane, dabco / thionyl chloride, under mild reaction conditions to afford symmetrical acid anhydrides in high isolated yields.
