Solid-phase Synthesis of sn-1,2- and sn-2,3-Diacylglycerols via Ring-Opening of the Glycidyl-Bound Resin

Seo, J.; Yoon, C.; Gong, Y. Solid-phase Synthesis of sn-1,2- and sn-2,3-Diacylglycerols via Ring-Opening of the Glycidyl-Bound Resin. J. Comb. Chem. 2007, 9, 366-369.

A general method developed for the parallel solid-phase synthesis of sn-1,2- and sn-2,3-diacyglycerol derivatives. The technique relies on the use of carboxylic acid-promoted epoxide ring-opening reactions of the glycidyl-bound resin 3. The polymer-bound monoacylglycerol 5, formed in this manner, is transformed to the respective polymer-bound diacylglycerols 7 and 9 by reaction of the free alcohol moiety with a second carboxylic acid under conditions that lead to retention or inversion of C-2 stereochemistry. The sequence is completed by BCl3-promoted cleavage of 7 and 9 to form the sn-1,2- and sn-2,3-diacylglycerols, respectively.
