Synthese und Reaktionen von 2-Deoxy-?-D-ribofuranosylderivaten von 3-Aryl-4H-pyrrolo[2,3-d]pyrimidin-4-iminen
摘要:
3-Aryl-7-(2-deoxy-beta-D-erythro-pentofuranosyl)-3,7-dihydro-4H-pyrrolo[2,3-d]-pyrimidin-4-imines (4) as well as 4-arylamino-7-(2-deoxy-beta-D-erythro-pentofuranosyl)-2-methyl-5-phenyl-7H-pyrrolo[2,3-d]pyrimidines (7) have been synthesized by glycosylation of the sodium salt of the corresponding nucleobases with 2-deoxy-3,5-di-O-p-toluyl-beta-D-erythro-pentofuranosyl chloride (2) followed by subsequent deprotection with sodium methoxide in methanol. The deprotected nucleoside 4 undergoes a Dimroth rearrangement on reflux for 24h in water to furnish the 4-arylamino nucleoside 7.
