Novel preparation of a 2′-O-acetyl-1′-O-(4-methoxybenzyl)-L- biopterin derivative, a versatile precursor for a selective synthesis of L-biopterin glycosides

L-Rhamnose was converted, over a 13-step-sequence, into 2′-O-acetyl-N2-(N,N-dimethylaminomethylene)-1′-O-(4- methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]-L-biopterin, an appropriately protected precursor of 1′-O- and 2′-O-monoglycosyl-L-biopterin.

Synthetic studies on pterin glycosides: the first synthesis of 2′-O-(α-d-glucopyranosyl)biopterin

l-Rhamnose was led, in a 14-step-sequence, to N2-(N,N-dimethylaminomethylene)-1′-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]biopterin (23), an appropriately protected precursor for 2′-O-glycosylation, while 4,6-di-O-acetyl-2,3-di-O-(4-methox
