Enantioselective synthesis of the phosphate esters of the immunosuppressive lipid FTY720
摘要:
The enantiomers of FTY720-phosphate (3) were synthesized via 2-methylene-4-(4-octylphenyl)butan-1-ol (7), 2,3-epoxy alcohol 8, and Delta(2)-oxazoline 10. These compounds have potential use in the treatment of autoimmune diseases and prevention of kidney transplant rejection. (c) 2005 Elsevier Ltd. All rights reserved.

In one embodiment of the present invention, a silicon-based cross-coupling reagent is disclosed which is a highly stable tetraorganosilicon compound allowing for a cross-coupling reaction under mild reaction conditions without using fluoride ions, transition metal promoter, or strong bases, and the residue of the silicon reagent can be recovered and reused. The silicon-based cross-coupling reagent is a silicon compound in which an o-hydroxymethylphenyl group is connected to a silicon atom for intramolecular activation.
