Synthese von Ara-Tubercidin und seiner 5'-Phosphate ueber Phasentransfer-Glycosylierung von 4-Amino-2-methylthio-7H-pyrrolopyrimidin

Phase transfer glycosylation of 4-amino-2-methylthio-7H-pyrrolopyrimidine (3a) with 2,3,5-tri-O-benzyl-1-bromo-D-arabinofuranose gives the anomeric nucleoside derivatives 4a/5a in 83percent yield.They are separated chromatographically and the ratio
