  摘要：

  N-Glycosylations of various heterocondensed uracils of the general type 4 are described. The thieno[2,3-d]pyrimidines (9a-e) afford with 1-0-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose (7) the corresponding 1-ribosides (10a-e) in a modified Hilbert-Johnson-Birkofer synthesis; from these 10a was smoothly saponified to give the free riboside 11a. - In a more generally applicable stereospecific sodium salt glycosylation procedure employing alpha-acetobromglucose, the 1-glucosides 12-16 and with beta-(trimethylsilyl)ethoxymethyl chloride (SEM-Cl) a variation of acyclonucleosides 17-22 have been obtained. The structure of 18a has been confirmed by X-ray analysis.
