| Outline of Final Research Achievements |
We examined asymmetric hydrolysis of 1,3-diacyl glycerol or its derivatives with lipases. Use of Lipase PS immobilized on ceramic was not effective to give only a low yield of the product. When 2-BOM- or 2-MOM-1,3-diacyl glycerols were used, Lipase PS worked very well to give the monoacylated glycerol in >90% de. Transformations into SQDG was next examined. Glycasilation of the diacylated glycerol with the imidate derived from sulfenylated glucose in the presence of TMSOTf gave a precursor to SQDG in good yield. Further transformations involving oxidation of the sulfur moiety and the removal of the protecting groups as well as application to a flow synthesis are under way.
