Abstract
Glycosylation of 2,6-diaminopurines or silyl derivatives thereof with a compound of the structure is facilitated by the presence of an optionally silylated 1,3-dicarbonyl compound during glycosylation. Byproducts are minimized, while stereoselectivity may be altered by choice of Lewis acid and other reaction condictions.
